How to find volume of shape using washer method​

Answer 1

Answer:

The formula for the volume of a washer requires both an inner radius r1 and outer radius r2. We'll need to know the volume formula for a single washer. V = π (r22 – r12) h = π (f(x)2 – g(x)2) dx. As before, the exact volume formula arises from taking the limit as the number of slices becomes infinite.
