You can put this solution on YOUR website!
I'm in your age category- you caught me on a good day
\n" ); document.write( "---------------
\n" ); document.write( "The circumference of the sphere would be:
\n" ); document.write( "\"+C+=+2%2Api%2Ar+\"
\n" ); document.write( "You are given:
\n" ); document.write( "\"+r+=+d%2F2+\"
\n" ); document.write( "\"+r+=+14%2F2+\"
\n" ); document.write( "\"+r+=+7+\"
\n" ); document.write( "and
\n" ); document.write( "\"+C=+44+\" in
\n" ); document.write( "---------------
\n" ); document.write( "\"+C+=+2%2Api%2Ar+\"
\n" ); document.write( "\"+44+=+2%2Api%2A7+\"
\n" ); document.write( "\"+44+=+14pi+\"
\n" ); document.write( "\"+44+=+43.98+\"
\n" ); document.write( "So, \"+44+\" is pretty close to \"+14pi+\"
\n" ); document.write( "---------------
\n" ); document.write( "The formula for the area of a sphere is: \"+A+=+4%2Api%2Ar%5E2+\"
\n" ); document.write( "( looked it up ) where \"+r+\" is the radius of the sphere
\n" ); document.write( "\"+A+=+4%2Api%2A7%5E2+\"
\n" ); document.write( "\"+A+=+4%2A49%2Api+\"
\n" ); document.write( "\"+A+=+615.752+\" in2
\n" ); document.write( "( so, actually, all you needed was the radius to find surface area )
\n" ); document.write( " \r
\n" ); document.write( "\n" ); document.write( "
