Determine the volume of a frustum of a cone if the diameter of the ends is 8 cm and 18 cm and its perpendicular height is 6 cm. Express answers in cubic cm in two decimal places.
=================
You can find this by extending the cone to a point and finding its volume, then subtracting the volume of the top part of the cone.

Or, you can use the formula for it:
Vol = (pi*h/3)*(r1^2 + r2^2 + r1*r2) where r1=9, r2=4 and h=6.
