Answer:

around 502.65

Explanation:

so, find the area of the circle first which is 16ft x 16ft x pi

after that, since a circle is 2 pi radians, just take 5/4 ÷ 2

then multiply that number over your area.

I'm not sure if I'm correct but this is what I know based on my limited understanding of it
