Acylinder is inscribed in a cube. if the edge of the cube is 3" long, find the volume of the cylinder.

21.2 cubic inches

Step-by-step explanation:

Supposing that the diameter of the cylinder match with the longitude of the edge of the cube (see figure attached); then, cylinder's diameter (D) and height (h) are equal to 3 inches.

The volume of the cylinder (V) is calculated as follows:

V = π*(D^2)/4*h

V = π*(3^2)/4*3

V = 21.2 cubic inches
