## Homework Statement

is it possible to find the of revolution about x axis volume of x=y^2+1 ,x=0 between y=1 and y=2

using washer method?

## Homework Equations

V=pi integral from a to b R^2-r^2 thickness

## The Attempt at a Solution

the problem is when I made the integral i had two inner radii first the line x =1 till the point x=1 because the parabola only starts there so I am confused do I just sum two integrals?

Edit I meant the first radius is line y =1 not x =1 sorry
