Question

I need some help on the following.. (40 Points!!)

Answer 1

The answer for the first picture is 648π or 2034.72

I got the answer using the formula πr squared times the height

so π9squared x 8

Answer 2

Answer:

648$\pi$   2: 5575.28 3:$\sqrt{17}$       -$\sqrt{17}$ 4: $\sqrt[3]{13}$

Step-by-step explanation:

1: volume of a cylinder  is base times height, base being (9^2)$\pi$ and height being well 8

2: equation for a volumes of a sphere is (4/3)$\pi$(11)^3

3: if you square something it turns positive and negative by some sort of magic

4: radical means in root notation
