Volume is a function of the square of the radius.

\n" ); document.write( "------------------
\n" ); document.write( "For the 10 inch pan:
\n" ); document.write( "\"V+=+pi%2Ar%5E2%2Ah+=+pi%2A100%2A3\"
\n" ); document.write( "V = 300 pi cubic inches
\n" ); document.write( "-------------
\n" ); document.write( "For 9 inch:
\n" ); document.write( "V = 300pi*81/100
\n" ); document.write( "V = 243 pi cubic inches
\n" ); document.write( "
