Find the exact volume of the solid that results when the triangular region with vertices at
a)

b)

(a)
To find:
The exact volume of solid that results when the triangular region with vertices
A triangle is drawn with the vertices
Then, it is rotated about
The resulting solid is a cone.
We have to find the volume of the cone.
Volume of the cone is given by the formula.
Substituting the radius and height
(b)
To find:
The exact volume of solid that results when the triangular region with vertices
