Hello!

To find the surface area of a cylinder you use the equation

[tex]2 \pi rh+2 \pi r^{2} [/tex]

You plug in the radius and the height

[tex]2 \pi (6)(15) + 2 \pi (15)^{2} [/tex]

when you put this into a calculator you get

Surface area is about 791.68in squared

The answer is 791.68in squared

Hope this helps!
