Question

Kirsten is trying to find height using the volume of a cylinder formula, V=πr2⋅h . Which of the following would be a good first step in re-arranging the formula to isolate the height? A) divide both sides of the equation by h B) multiply both sides of the equation by r C) divide both sides of the equation by π D) multiply both sides of the equation by h

Answer 1

C

Explanation:

we want to "isolate" h (height). that means "h" needs to be alone on one side of the equation, and all other factors need to be brought to the other side.

so, yes, we need to divide both sides by all factors of h : pi and r². only then will we have the isolated h on one side.

therefore, dividing both sides by pi is a good first step.
