You can put this solution on YOUR website!
The surface area of a sphere = $\"4%2Api%2Ar%5E2\"$

\n" ); document.write( " $\"324%2Api+=+4%2Api%2Ar%5E2\"$

\n" ); document.write( " $\"324+=+4%2Ar%5E2\"$

\n" ); document.write( " $\"81+=+r%2A2\"$

\n" ); document.write( "9=r.

\n" ); document.write( "The diameter is twice the radius = 2*9 = 18 inches.
