Question

Calculate the volume of a sphere that has a diameter of 7 meters.

Answer 1

1436.76

Explanation:

• use the formula 4piR^3 to solve

Answer 2

538.57 m³

Explanation:

The formula to find the volume of a sphere is:

V = 4 π r³

Given that,

diameter ⇒ 7 m

∴ radius = d / 2

radius ( r ) = 7 / 2 = 3.5 m

Let us find the volume now.

V = 4 π r³

V = 4 π × ( 3.5 )³

V = 4 π × ( 3.5 )³

V = 4 π × 42.875

V = 4 π × 42.88

V = 12.56 × 42.88

V = 538.57 m³
