Question

The formula S = 2πr^2 + 2πrh is used to find the surface area of a right circular cylinder. Solve this formula for h.​

Answer 1

Explanation:

WE NEED TO MAKE h THE SUBJECT OF THE FORMULA.

S =2πr² + 2πrh ( Taking 2πr² to the left side)

=> S – 2πr² = 2πrh

DIVIDING BOTH SIDES BY 2πr

=> h = (S– 2πr²)/2πr

HENCE, SOLVED FOR h

hope this helps :)
