$\"SA=4\"$ $\"pi\"$ $\"r%5E2\"$
\n" ); document.write( "
\n" ); document.write( "The variable is $\"r\"$ .
\n" ); document.write( "
\n" ); document.write( "The exponent is $\"2%7D%7D.%0D%0A+%0D%0AThe+product+%7B%7B%7B4pi\"$ is the coefficient.
\n" ); document.write( "Alternatively, we could say that $\"4\"$ and $\"pi\"$ are coefficients. \n" ); document.write( "
