diameter = circumference/pi
Radius is half the diameter and so 142/2 = 71 units
Radius is the square root of (71/pi) = 4.8 feet rounded to the nearest tenth
this plane is about 100 something feet in diameter
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.
71 cm = 2.33 feet (approx).71 cm = 2.33 feet (approx).71 cm = 2.33 feet (approx).71 cm = 2.33 feet (approx).
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
71 millimeters is 0.23 feet.
3,092,760 square feet = 71 acres
213 feet ( 3 feet in one yard so 71 yards X 3 feet = 213 feet)
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.
