Answer 2

i have to find the radius not the volume

Answer 3

you use @waterineyes formula and isolate the (r) algebraically

Answer 4

Then, alter the formula like this:
\[Radius = \sqrt{(3*Volume)/\pi h}\]

Answer 5

i got 5.75669

Answer 6

Take the square root of 5.75669... and get the answer...

Answer 7

and then by squaring it.. my answer is B (:
