## Volumes of solids of revolution

### Description

Find the volume of a solid of revolution

### Usage

shellmethod(f, a, b)

discmethod(f, a, b)


### Arguments

 f function of revolution a lower-bound of the solid b upper-bound of the solid

### Details

The functions discmethod and shellmethod implement the algorithms for finding the volume of solids of revolution. The discmethod function is suitable for volumes revolved around the x-axis and the shellmethod function is suitable for volumes revolved around the y-axis.

### Value

the volume of the solid
