Let 
be a nonnegative and continuous function on the closed interval ![[a,b]](https://mathworld.wolfram.com/images/equations/MethodofDisks/Inline2.svg)
, then the solid of revolution obtained by rotating the curve 
about the 
-axis from 
to 
has volume given by
![V=piint_a^b[f(x)]^2dx.](https://mathworld.wolfram.com/images/equations/MethodofDisks/NumberedEquation1.svg) |
