Question

A sphere has a radius of 6 meters. A second sphere has a radius of 3 meters. What is the difference of the volumes of the spheres?

Answer 1

Answer:

The difference between the volume of the two spheres is 791.6m^3.

Step-by-step explanation:

V = 4(pi)(r^3/3)

Sphere 1:

V = 4(pi)(6^3/3)

Solve.

V = 4(pi)(216/3)

V = 4(pi)(72)

V = 4(226.2)

V = (904.8)

Sphere 1 Volume: 904.8m^3

Sphere 2:

V = 4(pi)(3^3/3)

V = 4(pi)(27/3)

V = 4(pi)(9)

V = 4(28.3)

V = 113.2

Sphere 2 Volume: 113.2m^3

Subtract.

904.8 - 113.2 = 791.6

Answer 2

791.6
