The formula for the volume of a cone is 1/3 $\pi$ r²h, where r is the radius and h is the height.

Insert the values into the equation:

1/3 $\pi$ (5)²(11) ≈ 287.979327 (use a calculator for this part)

Divide 287.979327 by $\pi$ and convert the decimal to a fraction:

91.66666666666666666666666666666666666666... = 91 2/3

The volume of the figure is 91 2/3 $\pi$ cubic units or units³.
