Look at the formula for the volume of a cylinder below. v=π r²h which of the following equations can be used to find the height of h?

Well even though you didn't list ANY equations, this one is solved for "h"

h = V / (PI * r^2)

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
