Answer:
100π
Step-by-step explanation:
We have to find the height. Since we have the base and hypotenuse of the triangle, we can use the Pythagorean Theorem to find the side. We have c^2 - a^2 = b^2; 13^2 - 5^2 = 144; sqrt144 = 12. The height is 12 and the radius is 5, so using V = (1/3)πr2h, we get (1/3)π(25)(12) = 100π
