# Rotate the area bound by the following lines around the x-axis.

## Homework Statement

Rotate the area bound by the following lines around the x-axis.
y = x^2+1, y = -x^2+2x+5, x = 0, x = 3

## Homework Equations

None that are uniform enough to put here considering I'm fairly sure it's not washer...

## Homework Statement

Rotate the area bound by the following lines around the x-axis.
y = x^2+1, y = -x^2+2x+5, x = 0, x = 3
The first two equations are not lines. Their graphs are parabolas.
