Which expression can be used to find the volume of the cone in this composite figure?

A cylinder and cone. Both have a radius of 4 centimeters. The cylinder has a height of 7 centimeters and the cone has a height of 8 centimeters.

V = one-third pi r squared h = one-third (4) squared (8)
V = one-third pi r squared h = one-third pi (8) squared (4)
V = one-third pi r squared h = one-third pi (4) squared (7)
V = one-third pi r squared h = one-third pi (8) squared (8)
