Question

The following formula can be used to find the volume of a cylinder with radius, r, and height, h.


V=πr^2h

Which equation can be used to find the height of the cylinder if you know its volume and radius?

A. h = V - πr^2

B. h = V + πr^2

C. h = πr^2V

D. h = V/πr^2

Answer 1

original equation: v = PI r^2 h
 to solve for H divide both sides by PI x r^2

so H = V / PIr^2

 The answer would be D

Answer 2

original equation: v = PI r^2 h

to solve for H divide both sides by PI x r^2

so H = V / PIr^2

The answer would be D
