Final answer:

To solve the equation L = 3πrh + 5πr² for the variable h, rearrange the equation and isolate h on one side. The equation can be solved as h = L/(3πr) - 5r/3.

Step-by-step explanation:

To solve the equation L = 3πrh + 5πr², we can rearrange it to isolate the variable we want to solve for. In this case, let's solve for the variable h.

Step 1: Distribute the πr² to both terms in the equation.

L = 3πrh + 5πr² becomes: L = 3πrh + 5πr²

Step 2: Subtract 5πr² from both sides of the equation.

L - 5πr² = 3πrh

Step 3: Divide both sides of the equation by 3πr.

L/(3πr) - 5πr²/(3πr) = 3πrh/(3πr)

This simplifies to: L/(3πr) - 5r/3 = h

So, the equation is solved for h as h = L/(3πr) - 5r/3
