A frustum of a sphere of radius 13 cm is formed by two parallel planes on opposite sides of the center, each at distance of 5 cm from the center. Determine the volume of the frustum (a) by using the prismoidal rule, and (b) by using the formula for the volume of a frustum of a sphere
\n" ); document.write( "-------------
\n" ); document.write( "Find the volumes of the 2 segments NOT in the frustum:
\n" ); document.write( "For each:
\n" ); document.write( "\"V+=+pi%2Ah%5E2%2A%283r-h%29%2F3\" where r = 13 and and h = 6.5-5 = 1.5
\n" ); document.write( "\"V+=+pi%2A64%2839-1.5%29%2F3+=+800pi\" for each
\n" ); document.write( "---> 1600pi
\n" ); document.write( "-------------
\n" ); document.write( "Subtract that from the volume of the shpere:
\n" ); document.write( "---> \"4%2Api%2A13%5E3%2F3+-+4800pi%2F3+=+2396%2Api\" cc
\n" ); document.write( "------------------
\n" ); document.write( "h = the distance from the surface of the sphere to the plane on the diameter.
\n" ); document.write( "PS This is an equation used in the calculation of the volume of a liquid in a spherical tank where h would be the depth of the liquid.
\n" ); document.write( "========================
\n" ); document.write( "I mistakenly used 13 as the diameter when it's the radius.
\n" ); document.write( "The method is good, tho.
\n" ); document.write( "The student can redo it using 13 instead of 6.5
\n" ); document.write( "
\n" );
