document.write( "(Just to let you know the \"^2\" part just means squared. My computer doesn't have a key for make a squared 2 above a letter or number. And I also didn't have a pie button either, so I just typed the usual form of pie.) But what I was stuck on was find the volume, like you have to for the problem. If anyone knows how to go about solving this problem please oblige!! I would really appreciate it if anyone knew how to go about doing it. Thank you in advance! \n" );

Algebra.Com's Answer #172319 by rfer(16322)![]() ![]() ![]() You can put this solution on YOUR website! Your formula is for a Right Circular cone, you are solving a Frustum of a Right Circular cone. The part of a right circular cone between the base and a plane parallel to the base whose distance from the base is less than the height of the cone. \n" ); document.write( "V=Pi(R^2+rR+r^2)h/3 \n" ); document.write( "V=3.14(1.5^2+1*1.5+1^2)h/3 \n" ); document.write( "V=3.14(2.25+2+1)4/3 \n" ); document.write( "V=3.14*5.25*4/3 \n" ); document.write( "V=65.94/3 \n" ); document.write( "V=21.98 cu in \n" ); document.write( " |
