(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Consider the circle D on the plane with the center (2,0) and radius r=1. Revolving D about the y-axis, we obtain a donut (torus). What is the volume of this donut?

2. Relevant equations

Assume: [tex]

F(x)=\int^{a}_{-a} sqrt(a^2-u^2)du[/tex] = (PI * a^2 )/2 where a[tex]\geq0[/tex]

3. The attempt at a solution

I sincerely apologize, I have no idea as to where to even get started.
