Question

The volume of a sphere is 75716 cm3.
Work out the radius of the sphere.

Answer 1

Explanation:

Givens

V = 75716

pi = 3.14

r = ?

Formula

V = (4/3) pi * r^3

Solution

75716 = (4/3) * 3.14 * r^3 Multiply both sides by 3/4

75716 * 3/4 = 3.14 * r^3

56787 = 3.14 r^3 Divide by 3.14

56787 / 3.14 = 3.14 * r^3/3.14

18085 = r^3

∛18985 = ∛ r^3

r = 26.25
