There is a mathematical problem: the length of three sides of a right triangle is 3, 4 and 5. If you rotate each side as an axis for one circle, what geometry will you get? What are their volumes?

There is a mathematical problem: the length of three sides of a right triangle is 3, 4 and 5. If you rotate each side as an axis for one circle, what geometry will you get? What are their volumes?

The volume of the cone is 1 / 3 pie * 3 ^ 2 * 4 = 24 pie
The volume of the cone is: 1 / 3 pie * 4 ^ 2 * 3 = 32 pie
A combination of two cones with a common bottom is obtained by rotating around 5. Its volume is 1 / 3 pie (5 / 12) ^ 2 * 5
=48 pies / 5
