Can someone check this please? Thanks in advance =)

Answer 1

I think you are incorrect.

Answer 2

At first, the 2 bases (top and bottom I mean) would be 49π and 49π .
Also, you know that the surface of the round of the cylinder is height times circumference.
the circumference is 14π, and the height is 11.

Answer 3

So 252pi would be the surface area of the cylinder?
