In a right-angled triangle ABC, the sides are known AB = 5 BC = 4 AC = 3 find the diameter and height of the body obtained by rotating the indicated triangle around the leg AC BC
In both cases, when rotating, we get a cone.
1. The cone formed when rotating around the leg of the AC has:
– height h1 = AC = 3;
– base diameter d1 = 2 * BC = 8.
2. The cone formed when rotating around the leg of the BC has:
– height h2 = BC = 4;
– base diameter d2 = 2 * AC = 6.
Answer: in the first version, the base diameter is 8, the height is 3, in the second 6 and 4, respectively.
