Question

The volume of a sphere

Answer 1

Answer:

3 ft

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

36 pi = 4/3 pi r^3

Divide each side by pi

36 pi /pi= 4/3 pi r^3/pi

36  = 4/3  r^3

Multiply each side by 3/4

36 *3/4 = 3/4 *4/3 r^3

27 = r^3

Take the cube root of each side

27^ 1/3 = r^ 3 ^ 1/3

3 = r
