Company produces cylindrical water tanks.
If the height of a water tank is reduced from 10 feet to 5 feet and the radius is doubled, what will happen to the volume of the water tank?:
:
Write a vol of a cylinder equation for each scenario [V+=+pi%2Ar%5E2%2Ah]
let r = original radius
%28pi%2A%282r%29%5E2%2A5%29%2F%28pi%2Ar%5E2%2A10%29 = %28pi%2A4r%5E2%2A5%29%2F%28pi%2Ar%5E2%2A10%29 = 4%2F2 = 2
Canceled pi, r^2, 5 into 10
:
volume doubled
