the formula for the volume v of a sphere is 4/3(pi)r^3 . what is the radius of the basketball with a volume of 392 inches^3

Let's solve the volume equation for the radius: start with

Multiply both sides by 3:

Divide both sides by 4:

Divide both sides by pi:

Take the cube root of both sides:

Now, plug the value for V and you have the radius:

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
