A metallic sphere of radius of 21/2 cm is melted down and then recast into small cones of radius 7/2 cm and height 3 cm each.how many of such cones can be made.
\n" ); document.write( "----------
\n" ); document.write( "The volume of the sphere:
\n" ); document.write( "V = $\"4%2Api%2Ar%5E3%2F3+=+4%2Api%2A10.5%5E3%2F3\"$
\n" ); document.write( "V = 1543.5 pi cc
\n" ); document.write( "-----------------
\n" ); document.write( "Vol of each cone:
\n" ); document.write( " $\"v+=+pi%2Ar%5E2%2Ah%2F3+=+pi%2A3.5%5E2%2A3%2F3\"$
\n" ); document.write( "v = 12.25 pi cc
\n" ); document.write( "------------
\n" ); document.write( "1543.5 pi/(12.25 pi) = 126 cones
