## Homework Statement

I have to go around and find the volume of a silo-shaped trash can using solid of revolution

height 91cm

Circumference 119.3cm

Diameter 15cm

http://common.csnstores.com/United-Receptacle-European-Designer-15-Gal.-Round-Top-Receptacle~img~UR~UR1180_l.jpg is what the trash can looks like.

I need list of the equations(s) of the curve(s) which are going to be revolved around an axis. I also need to state the upper and lower limits for the equation(s). Then intergrate the curve(s)

## Homework Equations

I want to use [tex]\int[/tex] pi r^2 dx and from 0 to r

then do the volume of a sphere and divide by half.

But I believe this is wrong.

## The Attempt at a Solution

I tried that equation I wrote and was not right. I think I have to use the shells intergration but don't know the set up.
