Answer 1

I believe it is B

Answer 2

1 below B

Answer 3

The surface area of a cylinder is given by the formula 27²+2πrh, where r is the
radius and h is the height.
If the radius is equal to the height, we can substitute r for h in the formula:
2πr² + 2πr * r
This simplifies to:
4πr²

Answer 4

I believe it's C mostly because we take the formula of 2pir^2 + 2pirh which becomes 2pi^2 + 2pir^2 simplifying it we get. 4pir^2.
