• Circles - Diameter, Circumference, Radius and the Discovery of Pi Kathleen Ryan Randolph Magnet School 10409 S. ... Hoyne Chicago IL 60655 Chicago IL 60636 (773) 238-1554 (773) 535-9015 Objective: This seventh grade math lesson is designed to help students identify and measure the diameter, circumference, and radius of a circle. The students should discover the approximate value of pi through the relationship between the diameter and circumference. ... Identify the diameter, circumference, and radius of a circle. ... Demonstrate for the students how to measure the diameter and circumference on a circle. ... The students then measure the circumference using drywall tape. ... The circumference is recorded on the table worksheet. ... After the students have recorded the information for circles A-F, ask the students if they see a relationship between the diameter and circumference. ... Divide the circumference by the diameter for each circle. ... Discuss the results of circumference divided by diameter. ... Performance Assessment: The students will measure the diameter of a record album or another circular object (other than the previously used circles) and predict the circumference.

•   A normal child can have a head circumference which is borderline in either direction. ...
•   After 2 years of age the head circumference should be smaller than the chest circumference.   It has been documented that we Guatemalans, have a smaller head circumference than the one documented on the NCHS tables, the important data to consider is that the head should grow parallel to this tables as the rate of growth is really the important information to consider.

• The proportion that we use to calculate the circumference is: "The difference in the angles of the sun between the two sites is to 360 degrees as the north south distance between the two sites is to the total circumference. ... 133 is the distance in km for one degree latitude) Column 6: The formula for the circumference estimate =Abs(column 5*360/(difference in the angles between the top site and the current row)) (This comes from the proportion listed above. ) The formula for the % error, to be placed in G4: =((Column 6-40008)/40008)*100 (40008 km is the correct circumference) If this makes sense to you then you should go into the business to deciphering secret codes! If you use spreadsheets, however, it is pretty straight forward once you have a sheet in front of you and follow along. ...

• Ancient Measurements of the Circumference of the Earth.
• The reconstruction of the system of ancient lineal units allows to confirm the conclusion of French scholars of the eighteenth and early nineteenth centuries that the ancients had achieved a most accurate calculation of the circumference of the earth and that this calculation had been performed earlier than Greek times. The French scholars concluded that all the estimations reported by authors of the Hellenistic and Greek period repeat, according to different stadia, the statement of Aristotle that the mathematikoi had calculated the circumference of the earth as 400,000 stadia. ... Böckh, who tried to prove that all units of length, volume, and weight, could be calculated from a single unit of length, based himself on the studies of Gosselin and Letronne who in 1822 had tried to prove, each on his own way, what had become for almost a century a tenet among the members of the French Académie des Sciences and Académie des Inscriptions, namely, that all ancient reports are based on a single pre-Greek calculation of the circumference of the earth. ...
• Aristotle (On the Heavens II, 298 B) reports that those mathematikoi who try “to calculate the circumference by proportional calculations” (analogizesthai peirontai), calculate the circumference as 400,000 stadia. ...
• The wording of Aristotle may refer to the fact that the ancients knew that the value of the degree varied from degree to degree, and hence could infer the circumference “by analogy” or “by proportional calculations” from the length of the degree at latitude 36°.
• The stadion mentioned by Aristotle is equal to 300 barley feet; if the feet are of the trimmed variety the circumference of the earth would be 39,952,644 m. ...
• The Greek geographers of the Roman period report the figure of 240,000 and 180,000 stadia for the circumference. ...
• Kleomedes reports that Eratosthenes calculated the latitude of Alexandria in Egypt and that of Syene at the First Cataract, and found that this distance, which is the entire length of Egypt, would be 1/50 of the circumference of the earth. Eratosthenes would have calculated the distance between Alexandria and Syene as 5000 stadia, so that the circumference is 250,000 stadia. ...
• Letronne, following remarks made by other scholars before him came to the conclusion that Eratosthenes did not rely on any actual survey on the ground in order to calculate the length of the degree, but merely calculated the latitude of Alexandria and of Syene and having found it to be 1/50 of the circumference of the earth, applied to it an established figure of the value of such an arc of circumference on the basis of a known value of the length of a degree. ...
• There is a score of articles trying to prove in detail that Eratosthenes proceeded to an independent evaluation of the circumference of the earth; but even though some of them show great ingenuity, none succeeds. The result ascribed to Eratosthenes, that is, a circumference of 250,000 stadia, repeats the traditional datum. ...
• Archimedes (Sand Reckoner) speaks of the circumference of the earth as a datum that does not need any particular discussion and estimates it as 300,000 stadia. ... The circumference is 135,000,000 Roman feet or 75 miles to the degree. ...
• In substance, Eratosthenes did not intend to calculate the length of the degree or the circumference of the earth, which were well known current data. ... To this effect he quoted Egyptian data to the effect that the extension of the country is 1/50 of the circumference of the earth. ...

• Antenatal Waist Circumference and Hypertension Risk .
• Objective: To assess whether waist circumference at the first antenatal visit predicts risk of developing hypertension later in pregnancy. ...
• Results: The median waist circumference between 6 and 16 weeks’ gestation was 79 cm (interquartile range 72–84 cm), and there was no significant relationship between waist circumference and gestational age. Greater waist circumference was noted in subjects who subsequently developed pregnancy-induced hypertension (median 81 versus 77 cm, Mann-Whitney U test, P =. ... The conventional, nonpregnant waist circumference action level of 80 cm gave a Mantel-Haenszel odds ratio (OR) for pregnancy-induced hypertension of 1. ...
• Conclusion: We conclude that waist circumference up to 16 weeks’ gestation can predict pregnancy-induced hypertension and preeclampsia. Therefore, waist circumference could form the basis for health promotion involving raising awareness of the importance of or urging weight reduction for women planning pregnancies. ...

• Eratosthenes, a Greek astronomer, mathematician, geographer, scientific writer and poet made a surprisingly accurate estimate of the earth's circumference. ...
• Eratosthenes could now measure the circumference of the earth by making two assumptions--that the earth is round and that the sun's rays are essentially parallel.
• Knowing also that the arc of an angle this size was 1/50 of a circle, and that the distance between Syene and Alexandria was 5000 stadia, he multiplied 5000 by 50 to find the earth's circumference. ... Where d = distance  between Syene and Alexandria, A = 360 degrees assumption of round earth, a = shadow angle of vertical stick, D = to be determined (circumference).
• His calculation of the earth's circumference as being 252,000 stadia is equivalent to 24,662 miles, or within 250 miles of the correct figure. ...
