Can someone please look at these three problems and explain to me. I have gotten them wrong more than twice and have given up. 1. The region bounded by the given curves is rotated about the x-axis. y = -x**2 +7 x - 12, y = 0 Find the volume V of the resulting solid by any method. V = 2. The region bounded by the given curves is rotated about x = 8. x = 1 - y**4, x = 0 Find the volume V of the resulting solid by any method. 3. The region bounded by the given curves is rotated about y = 5. x = (y - 7)**2, x = 4. Find the volume V of the resulting solid by any method thank you very much.
