Answer:

3) 81.5 in²

Steps:

D = 32/π = 10.18..

r = 10.18/2 = 5.09

A = π × r²

A = π × 25.93

A = 81.48 ≈ 81.5 in²

in one formula:

A = π(32/π × 1/2)²

A = 81.5 in²

Answer:5.09 sq. inches

Explanation:

C = 2π × r

32 = 2π × r


(32)/(2\pi ) = r

r = 5.09295817894, rounded equals 5.09, so, option 1 is correct
