Explanation:

Diameter = 20.6


radius = (diameter)/( = 2) = (20.6)/(2) = 10.3 \: ft \\ \\ c = \pi \:d = 3.14 * 20.6 = 64.68 \: ft \\

Explanation:

Radius is half of the diameter

Circumference is 2*pi*radius

Area is pi*radius^2

So r (radius)= 10.3

C (circumference)=64.72

and A (area)=333.29

feel free to ask more questions :)
