The height of a cylindrical vessel that will hold 20 liters is equal to the diameter. Find the altitude and the radius.
------------
Vol+=+pi%2Ar%5E2%2Ah
Since h = 2r
Vol+=+2pi%2Ar%5E3+=+20 in liters
Vol+=+2pi%2Ar%5E3+=+20000 in mls or cubic cms
Solve for r
h = 2r

vol=pi%2Ar%5E2%2Ah
h=d=r/2
so
vol=pi%2Ar%5E2%2A%28r%2F2%29
2*vol=pi%2Ar%5E3
2%2A20=pi%2Ar%5E3
%2840%29%2F%28pi%29=r%5E3

cube+root+of+%2840%29%2F%28pi%29=r
how to insert cube root here??
altitute or height is %2820%29%2F%28pi%29/
