You can put this solution on YOUR website!
The formula for surface area of a cone is $\"%28pi%29%28r%5E2%29%2B%28pi%29%28r%29%28L%29\"$ , where r is the radius and L is the slant height. Basically, you are finding the area of the circular base and the area of the lateral face. The diameter is twice the radius, so if we divide 28 by 2, we get 14 cm. If we set up our equation...

\n" ); document.write( "So $\"504pi\"$ $\"cm%5E2\"$ is your answer. \n" ); document.write( "
