You can put this solution on YOUR website!
Well, let's see if you got it!
\n" ); document.write( "The surface area (S) of a sphere is given by:
\n" ); document.write( "\"S+=+4%28pi%29r%5E2\" where r is the radius of the sphere.
\n" ); document.write( "In this problem, r = 15 ft, and we can use\"%28pi%29+=+3.14\" as an approximation.
\n" ); document.write( "\"S+=+4%283.14%29%2815%29%5E2\"
\n" ); document.write( "\"S+=+2826\"sq.ft.\r
\n" ); document.write( "\n" ); document.write( "So you are right on!\r
\n" ); document.write( "\n" ); document.write( "
