Question

Marta is solving the equation S = 2πrh + 2πr2 for h. Which should be the result?

Answer 1

Answer:  h = (S - 2πr²) / 2πr

Step-by-step explanation:

Since we are given that

S = 2πrh + 2πr²

Subtracting by 2πr² on both sides we get

S - 2πr² = 2πrh

Dividing by 2πr on both sides we get

(S - 2πr²) / 2πr = h

So

The final equation is

h = (S - 2πr²) / 2πr
