The top and bottom radius of a conical frustum are 1 cm and 4 cm by each,

the central angle of the slant surface is 216 degrees,

what is the volume of the conical frustum?

The model is defined as

class ConicalFrustumByTwoCones

{

factor angle, volume;

Cone m, n;

angle = m.slant.angle = n.slant.angle;

m.t.A = n.t.A;

volume = n.volume - m.volume;

}

Query is made as

*select volume from ConicalFrustumByTwoCones*

*where angle=216/PI, m.bottom.r=1, n.bottom.r=4*

The volume is around 3.49 cubic centimeters.
