Question

I cant figure this problem can you guys help/

Answer 1

r = 6.998 in

D = 13.996 in

C = 43.9697 in

Explanation:

Area = π
`r^2`

153.86 = π
`r^2`

153.86/π =
`r^2`

sq root(153.86/π) = r ≈ 6.998 in

Diameter = 2r

D = 2(6.998) = 13.996 in

Circumference = 2πr

C = 2π(6.998)

C = 13.996π ≈ 43.9697 in

Hope this helps!
