A spherical bowl of radius 10 is filled with oil to such a depth that the oil surface is equal to 75(pi) square cm. Compute the volume of the oil and find the area covered by the oil in the tank.
\n" ); document.write( "---------------
\n" ); document.write( "The radius of the surface is sqrt(75) cm.
\n" ); document.write( "d = depth of oil
\n" ); document.write( "75 = d*(20-d) (products of chords)
\n" ); document.write( "d^2 - 20d + 75 = 0
\n" ); document.write( "d = 5, d = 15 cm
\n" ); document.write( "------
\n" ); document.write( "I'll find the area and volume later today.
\n" ); document.write( "
\n" ); document.write( "
\n" );
