1 25 12 divided by 2 divided by 3 14 divided by 2 to calculate the radius and volume.

Let the radius of the bottom surface of the cylinder be r and the height of the cylinder be r.

2πr×r=50.24

2×3. 14×r？ =50.24

6.28r？ =50.24

r？ =8

Therefore, the bottom area of the cylinder is:

8×3. 14=25. 12 (square centimeter)

The surface area of this cylinder is:

25. 12×2+50.24

=50.24+50.24

= 100.48 (square centimeter)

A: The surface area of this cylinder is 100.48 square centimeter.
