Algebra.Com's Answer #230044 by Greenfinch(383) You can put this solution on YOUR website! Hemisphere is of radius 10 foot, so volume is 1/2(4/3 pi r^3) or 2/3 pi x 1000. \n" ); document.write( "Cylinder is 60 foot high and 10 foot radius, or 60 x 100 x pi. \n" ); document.write( "Total is thus 1/3(2000pi + 18000pi) or (20000/3)pi \n" ); document.write( "The question is a little odd in that it might be construed as a cylinder 60 foot high overall (that is, including the hemisphere)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
