As you know the surface are of the sphere is given by the formula:\r
\n" ); document.write( "\n" ); document.write( "\"A=4%2Api%2Ar%5E2\", substituting we get:\"100%2Api=4%2Api%2Ar%5E2\"=>\"r%5E2=25\"=> \r
\n" ); document.write( "\n" ); document.write( "\"r=5\"cm, since we know the radius easy can find the volume by the formula:\r
\n" ); document.write( "\n" ); document.write( "\"V=%284%2F3%29%2Api%2Ar%5E3\", substituting we get:\"V=%284%2F3%29%2Api%2A5%5E3\"=>\r
\n" ); document.write( "\n" ); document.write( "=>\"V=%28500%2Api%2F3%29cm%5E3\".
\n" ); document.write( "
\n" );
