Answer 2

Answer:

2xy

Step-by-step explanation:

The volume V of a cone with radius r is one-third the area of the base B times the height h .

V=13Bh  or  V=13πr2h,  where  B=πr2

Note : The formula for the volume of an oblique cone is the same as that of a right one.

The volumes of a cone and a cylinder are related in the same way as the volumes of a pyramid and a prism are related. If the heights of a cone and a cylinder are equal, then the volume of the cylinder is three times as much as the volume of a cone.
