volume of solid cylinder= =3.14*(6*6)*8 =πr^2h 904.32
volume of conical cavity = 1/3(πr^2h ) = 1/3(904.32) = 301.44cm^3
volume of resulting solid = 904.32 - 301.44 = 602.33cm^3
volume of conical cavity = 1/3(πr^2h ) = 1/3(904.32) = 301.44cm^3
volume of resulting solid = 904.32 - 301.44 = 602.33cm^3
