document.write( "Question 831408: what dimensions of a tin can of volume 54 pie cm^3 should be produced if the required height is equal to the diameter of its base \n" ); document.write( "
Algebra.Com's Answer #501305 by Elomeht(22)![]() ![]() ![]() You can put this solution on YOUR website! 1. The volume of the can (assumed cylindrical) is given by the formula: \n" ); document.write( " V = PI (r^2) h where r is the radius of the base and h is the height\r \n" ); document.write( "\n" ); document.write( "2. Since the height is equal to the diameter of the base (i.e. 2r), we can modify \n" ); document.write( " the formula to read: \n" ); document.write( " V = PI (r^2)2r = 2PI (r^3)\r \n" ); document.write( "\n" ); document.write( "3. We are told that the volume of the can is 54PI cubic centimeters, so we can put: \n" ); document.write( " 54PI = 2PI (r^3)\r \n" ); document.write( "\n" ); document.write( "4. From the above, 27 = (r^3), so r = 3\r \n" ); document.write( "\n" ); document.write( "5. The diameter of the base is therefore 6, which is the same as the height \n" ); document.write( " \n" ); document.write( " |
