Question

Determine the volume of a sphere if it has a radius of 5 inches

Answer 1

Answer: 523.25 in^3

Explanation:

Radius (r) = 5 in
Volume = 4/3πr^3

Therefore,
=> 4/3πr^3
= 4/3 * π * r * r * r
= 4/3 * 3.14 * 5 * 5 * 5
= 4/3 * 3.14 * 125
= 4.186 * 125
=> 523.25

Volume = 523.25 in^3

Answer 2

V ≈ 523.6in³

Explanation:

Using the second sphere volume equation results in:

4/3 x 3.14159 x 53 = 4.1866 x 125 = 523.6in3
