Steps:

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

Substitute the value of the radius r = 40.0 in height h = 20.0 in into the formula to find the volume. Pi (π) is approximately equal to 3.14 .

π x 402 in2 x $20\above 1pt3$ in

Raise 40 in power of 2

π x 1600.0 in2 x $20\above 1pt3$ in

Divide 20 by 3

π x 1600.0 in2 x 6.6666667 in

Multiply 1600.0 in2 and 6.6666667 in

π x 10666.66672 in3

Combine π and 10666.66672 in3

The result can be shown in multiple forms.

Exact Form

Volume = 10666.66672π in3

∴ Volume of Cone radius 40 in and height 20 in is 10666.66672π in3

Decimal Form

Volume = 33493.3335008 in3

∴ Volume of Cone radius 40 in and height 20 in is 33493.3335008 in3
