Volume of a Cone Radius 81 foot by 64 foot Calculator

The Volume of a Cone is equal to the area of the base π r² times the height h/3 . If volume of a cone radius 81 foot by 64 foot is 439499.5193133 foot³.

Steps:

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

Substitute the value of the radius r = 81.0 ft height h = 64.0 ft into the formula to find the volume. Pi (π) is approximately equal to 3.14 .

π x 81² ft² x $64\above 1pt3$ ft

Raise 81 ft power of 2

π x 6561.0 ft² x $64\above 1pt3$ ft

Divide 64 by 3

π x 6561.0 ft² x 21.3333333 ft

Multiply 6561.0 ft² and 21.3333333 ft

π x 139967.9997813 ft³

Combine π and 139967.9997813 ft³

The result can be shown in multiple forms.
