Sorry, i can't help you with this question, because you never provide the picture of the cylinder, but here is the formula of the cylinder and the steps how to find it.
Step-by-step explanation:
Formula: A=2πrh+2πr2
Add the area of every end plus the surface of the side to find the surface of the cylinder. Each end is a circle so that each end's surface area is β*r2, where r is the end's radius. The total region is 2 ′ * r2. There are two sides.
The answer would be 11 because the x's 9 doesnt have to move because they're on the same point. If you take 7 away from -7 you get zero. Add 4 to that 7 and you get 11. Make sesnse? Hope this helped!
