Find the surface area of the cylinder to the nearest tenth of a square unit with a radius of 3cm and a height of 18.2 cm. use 3.14 for pi.

To find the area of this cylinder, you will need to find the area of each circular base and the area of the curved surface.  The curved surface is in the shape of a rectangle when laid out flat.  

The formula used to find the surface area is 2 x pi x r^2 (area of the faces) + pi x d x h (area of the curved surface which is the diameter times the height).  

Substitute the values in and it would be 2 x 3.14 x 3 x 3 + 3.14 x 6 x 18.2.  The surface area would be approximately 399.4 square cm.  This is approximate because pi is rounded.
