Answer:

(3V) / (πr^2) = h

Explanation:

We can solve for h using the following steps:

Step 1: Multiply both sides by 3:

(V = 1/3πr^2h) * 3

3V = πr^2h

Step 2: Divide both sides by πr^2 to solve for h:

(3V = πr^2h) / πr^2

(3V) / (πr^2) = h

Optional Step 3: Check the validity of the answer:

If we were to use 4 for r and 5 for h, we'd get a volume of 83.7758041 units cubed:

V = 1/3π(4)^2 * 5

V = 1/3π * 16 * 5

V = 80/3π

V = 83.7758041

Now we can use 3V / πr^2 and see if we get 5 for h to check whether we've correctly solved for h:

(3(83.7758041)) / (π * 4^2) = 5

(251.3274123) / (16π) = 5

5 = 5

Thus, our answer is correct.
