The formula for the volume of a sphere is
V= 3 #rº. What is the formula solved for r?

Answer 1

B. r = 3√(3V - 4π)

Explanation:

volume of a sphere,V = 4/3πr³

Solve for r

V = 4/3πr³

V - 4/3π = r³

r³ = V - 4π/3

Cross product

r³ = V*3 - 4π

r³ = 3V - 4π

Find the cube root of both sides

3√r³ = 3√(3V - 4π)

r = 3√(3V - 4π)
