Blog number is unknown

Since all our problems have integrating in it, i will talk about integration as a review. All integration is is doin the opposite of takin the derivative. Instead of multiplyin the coefficient by the exponent then subtractin one from the exponent like you do when you take the derivative, you ADD one to the exponent and DIVIDE the coefficient by the exponent. Another thing is for these section you need to know how to graph the equations and
how to find there reflections on a graph.

We learned how to solve for volume, which you have some different formulas to use.
One of those formulas is (pi)S(r^2)dx
Another formula is (pi)S(top^2)-(bottom^2)dx
When you have any problem where you are solving for volume, you need to square the
equation first, then you would integrate like usual and plug in the bounds. But while doing this keep the pi out front and do not add it until the end.
