Question

How do you find the Volume of a disc with radius=z and depth=a?

I have problems substituting it into the formula.

Answer 1

Are you using the Washer Method?

Answer 2

A disc, with a depth, is just a cylinder. The volume of a cylinder is \(V=\pi r^2 h\). In your example, with no numbers, you simply plug in your letters, \(V=\pi z^2 a\)

Answer 3
