Hello to you!

To find the height you will need the formula of the volume of a cylinder, which is :

V = π ∗ r2 ∗ h

You can then replace the values ​​that you know so you will have:

250 = π ∗ 12 ∗ h

After that, you will have to isolate the variable you are looking for, which is h.

To do that, you have to divide the two sides of the equation by the coefficient of the variable, which is π * 12. Then, all that is left is to perform the division to find h!
