Question

The formula for the volume of a sphere is V=4/3πr^3. What is the formula solved for r?

Answer 1

The formula for the volume of a sphere is V=4/3πr^3. Find the radius of a sphere with each volume. 
1. 10 in^3

Solve for r



r =~ 1.3365 inches

Answer 2

$V= \frac{4}{3} \pi r^3$

$\frac{3}{4}V= \pi r^3$

$\frac{3}{4}V* \frac{1}{ \pi } = r^{3}$

$r^{3} = \frac{3V}{4 \pi }$

$r = \sqrt[3]{ \frac{3V}{4 \pi } }$
