Circumference of a circle formula
c = 2 π r
c / 2π = r . . . Use this formula
70 / 2(3.141592654) = r
70 / 6.283185307 = r
11.14084602 = r
The radius is 11.14084602 feet

Circumference = pi times the diameter, so diameter = circumference divided by pi. You get 70 *7/22 = 22.28 feet, which is just over 22 feet, 3 inches.

pie*Diameter=circumference
> 3.14*D=70
> D=70/3.14
now solve it.

22.29 ..... it is 70 feet divided by 3.14 (pi) the ratio of diameter and circumference..... so diameter times 3.14 = circumference
