Answer:

Radius = 16 ft

Diameter = 32 ft

Area = 803.84 ft²

Circumference = 100.48 ft

Explanation:


Diameter=32\ ft\\\\Radius=(Diameter)/(2)\to Radius=(32\ ft)/(2)=16\ ft\\\\\text{The formula of an area of a circle:}\\\\A=\pi r^2\qquad(r-radius)\\\\\pi\approx3.14\\\\\text{Substitute:}\\\\A=\pi(16^2)=256\pi\ ft^2\approx(256)(3.14)=803.84\ ft^2\\\\\text{The formula of a circumference:}\\\\C=2\pi r\\\\\text{Substitute:}\\\\C=2\pi(16)=32\pi\ ft\approx(32)(3.14)=100.48\ ft
