Using the equation for a frustum
\n" ); document.write( "Volume = Pi* h/3 * (R^2 + Rr + r^2)
\n" ); document.write( "R = large radius
\n" ); document.write( "r = small radius
\n" ); document.write( "h = height
\n" ); document.write( "Volume = Pi*20/3 * (24^2 + 24*16 + 16^2)
\n" ); document.write( "Volume = 25467.8cm^3
\n" ); document.write( "Hope this helps.
