Answer:

Explanation:
The volume of a sphere is calculated using the following formula:

The volume of the sphere is
. Substitute this value in for v.

We are solving for the radius, so we must isolate the variable r. It is being multiplied by 4/3π. We can divide by this fraction or multiply by the reciprocal. The reciprocal is the fraction flipped, or 3/4π



The variable is being cubed. The inverse of a cube is the cube root, so we take the cube root of both sides of the equation.
