what's the circumference of a great circle on that sphere? Use 3.14 for pi.

Question

If the volume of a sphere is 374 cubic inches, what's the circumference of a great circle on that sphere? Use 3.14 for pi.

Answer 1

Volume = 374 in³ = (4/3)π r³ 

 

374 (3/4) /π  in³ = r³

 

89.26 in³ = r³

4.47 in = r

 

Circumference = 2πr = 2π(4.47 in) = 14.04 in
