\n" ); document.write( "\"V=%284%2F3%29%28pi%29r%5E3\"
\n" ); document.write( "So if the diameter is 2.5 inches, the radius is (2.5)/2 inches, which is 1.25 inches. So the volume of the tennis ball is
\n" ); document.write( "\"V=%284%2F3%29%28pi%291.25%5E3\"
\n" ); document.write( "\"V=%284%2F3%29%28pi%29%281.953125%29=8.2\"
\n" ); document.write( "So volume is 8.2 in^3.
