d = 2r
Circumference = 2*pi*r
71 = 2*pi*r
r = 71/(2*pi)
2r = d = 71/pi
d = 22.6 approximately
diameter = circumference/pi
To find the diameter from the circumference, you can use the formula ( C = \pi d ), where ( C ) is the circumference and ( d ) is the diameter. Rearranging the formula gives ( d = \frac{C}{\pi} ). Plugging in the circumference of 71 inches, the diameter is approximately ( \frac{71}{3.14} ), which is about 22.6 inches.
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.
The SR-71 Blackbird has a top speed of approximately 2,200 miles per hour (3,540 kilometers per hour). The circumference of the Earth is about 24,901 miles (40,075 kilometers). At maximum speed, it would take around 11.3 hours for the SR-71 to circle the Earth, assuming it could fly continuously without refueling or any other limitations.
213 feet ( 3 feet in one yard so 71 yards X 3 feet = 213 feet)
3,092,760 square feet = 71 acres
