Question

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

Answer 1

Answer:

Lette answer is A

Step-by-step explanation:

Answer 2

Answer:

h = $\frac{S}{2πr}$ - r

Step-by-step explanation:

The question requires you to make h the subject of the formula.

S = 2πrh + 2πr²

subtract 2πr² on both sides.

S - 2πr² = 2πrh - 2πr² -  2πr²

S - 2πr² = 2πrh

Dividing both sides by  2πr

(S -  2πr²)/2πr =  2πrh/ 2πr

h = $\frac{S}{2πr}$ - r
