Question 778654
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*r^2*h}}}]
let r = original radius
{{{(pi*(2r)^2*5)/(pi*r^2*10)}}} = {{{(pi*4r^2*5)/(pi*r^2*10)}}} = {{{4/2}}} = 2
Canceled pi, r^2, 5 into 10
:
volume doubled
