A way of understand would be using the expression (square root)4. 4 can be changed to 2^2. The power WITHIN the root will then be 2, which will be the numerator of the fraction. The power OF the root itself is 2 as well, which is the denominator of the fraction. This will leave us with 2^(2/2) = 2^1 = 2, which is correct; square root of 4 is 2 indeed.
Hope this helps! :)

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
