Best Answer

d = 2r

Circumference = 2*pi*r

71 = 2*pi*r

r = 71/(2*pi)

2r = d = 71/pi

d = 22.6 approximately

How did Archimedes discover pi?

Archimedes found a method for finding good approximations to the ration of the circumference of a circle to the diameter. He did this by inscribing polygons inside the circle and finding how the perimeter changes when the number of sides is doubled. Archimedes came up with an approximation that is equivalent to saying that pi is between 3 1/7 and 3 10/71. This is quite far from being as accurate as what you showed.

How many laps around a 16 foot round pool make a mile?

Well, actually if you attain the circumference of the collection of liquid by taking the diameter of 24 feet and multiplying it by pi which is approximately 3.14159265 you would come to an answer of 75.3982236 feet. And by taking the number of feet that exists in a mile which is 5,280 and divide that by the circumference you would get 70.02817504. Therefore we would have to proceed around the pool generally just under 71 times its simple math really, but this also does not include that we are traveling the vortex internally and not on the full exterior of the figure. so genuinely the fact is we'd have to go a slightly prolonged distance to achieve an exact mile. =D

Who discovered the relationship between the diameter and circumference of a circle?

The Greek mathematician Archimedes was the first to approach the subject mathematically. He came to the conclusion that pi (the constant that was at the center of the relationship) had a value somewhere between 223/71 en 22/7. The average was 3,141851. Pretty close. Later a Chinese mathematician called Liu Hui came even closer with a better approximation.
