Steps:

Volume of Cone π x radius2 x $height\above 1pt3$

Substitute the value of the radius r = 13.0 in height h = 81.0 in into the formula to find the volume. Pi (π) is approximately equal to 3.14 .

π x 132 in2 x $81\above 1pt3$ in

Raise 13 in power of 2

π x 169.0 in2 x $81\above 1pt3$ in

Divide 81 by 3

π x 169.0 in2 x 27.0 in

Multiply 169.0 in2 and 27.0 in

π x 4563.0 in3

Combine π and 4563.0 in3

The result can be shown in multiple forms.

Exact Form

Volume = 4563.0π in3

∴ Volume of Cone radius 13 in and height 81 in is 4563.0π in3

Decimal Form

Volume = 14327.82 in3

∴ Volume of Cone radius 13 in and height 81 in is 14327.82 in3
