Consider the following formula used to find the volume of a cone.

V = πr^2 h/3 < - - - In words, this is pi r squared times h over 3, it's all one thing.

Which of the following represents the formula that could be used to find the height of the cone?

A = h=π r^2 over 3V

B = h=3V over π r^2

C = h=3π r^2 over V

D = h=V over 3π r^2

To get rid of the denominator, you have to multiply each side by three, which leaves πr^2 h = 3V, then to get h alone, you need to divide by πr^2 (Since that's being multiplied by h, you wouldn't subtract), so the end equation would be B.
