Question

Find the volume of the sphere that has a surface area of 720 in2. Round your answer to the nearest tenth.

Answer 1

1816.7

Explanation:

Surface area = 4πr² = 720

r = √(720/4π)

Volume = 4/3×π×r³

= 1816.7

Answer 2

Volume of sphere = 1817 inch³

Explanation:

Given:

Surface area of sphere = 720 inch²

Find:

Volume of sphere

Computation:

Surface area of sphere = 4πr²

720 = 4(3.14)r²

720 = 12.56r²

r² = 57.32

radius = 7.57 inch

Volume of sphere = (4/3)(π)(r)³

Volume of sphere = (4/3)(3.14)(7.57)³

Volume of sphere = 1817.09

Volume of sphere = 1817 inch³
