Volume  of the cylinder = 3 times volume of the cone

The base of the radius  is r = 4

The height is h = 6

Volume of the cylinder v1 = π * r2 * h

Substitute r  = 4 and h = 6 in the v1

There v1 = π* 42 * 6

v1 = 96pi

Volume of the cone v2 = 1/3πi * r2 * h

Substitute v1 = π* r2 * h

v2 = 1/3v1

Substitute v1 =96π

There fore v2 = 1/3(96π)

v2 = 32π.
