31113.04 in
9(1017.36 in
9.254.34 in

Answer 1

I can confirm that the answer is 3(254.34 in.2). I did it on Odyssey

Explanation:

Answer 2

my answer is a bit different but kinda similar ig.

254.34in^2

Explanation:

Radius = Diameter/2 18/2 = 9

Area of circle= pi(3.14) x r^2

A= (3.14) x 9^2

A= (3.14) x 81

A= 254.34in^2
