Steps:

Volume of Cylinder π x (radius)2 x (height)

Substitute the value of the radius r = 21.0 in height h = 15.0 in into the formula to find the volume. Pi (π) is approximately equal to 3.14 .

π x 212 in2 x 15 in

Raise 21 in power of 2

π x 441.0 in2 x 15 in

Multiply 441.0 in2 and 15 in

π x 6615.0 in3

Combine π and 6615.0 in3

The result can be shown in multiple forms.

Exact Form

Volume = 6615.0π in3

∴ Volume of Cylinder radius 21 in and height 15 in is 6615.0π in3

Decimal Form

Volume = 20771.1 in3

∴ Volume of Cylinder radius 21 in and height 15 in is 20771.1 in3
