Volume of revolution (single integral vs triple integral)

We will find the volume of revolution of the solid generated by rotating the region bounded by y=x^2, y=9, x=0, about the y-axis. This is a typical calculus 1 problem but today we will make it 3x more fun (and get calculus 3). 🛍 Shop my math t-shirts & hoodies: 👉 https://amzn.to/3qBeuw6 👉 Support this channel and get more content   / blackpenredpen   #blackpenredpen #calculus
