A cone and a pyramid are both 3 inches in height. If the radius of the base of the cone is 4 in and the a side of the square bas e of the pyramid is 2π in, which has the larger volume?
2 answers:
Pyramid=1/3(hside^2) h=3 for both side for pyramid is 2pi pyramid=1/3(3(2pi)^2) pyramid=4pi^2 cone=1/3hpir^2 h=3 r=4 cone=1/3(3)(pi4^2) cone=pi16 cone=16pi 16pi compared to 4pi^2 divide both sides by 4pi 4 compared to pi 4>pi because pi is about 3.14 so cone has larger volume
I got the answer of the cone
