Answer:
The volume of Cone B is twice the volume of Cone A.
Explanation:
The volume of a cone is given by
V = 1/3 pi r^2 h where r is the radius and h is the height.
Cone A
d = diameter
r = radius
h = height
V = 1/3 pi r^2 h
Cone B
The diameter is double the diameter of A.
2d so the radius is 2r
The height is half the height of A.
1/2 h
Substitute into the equation for volume.
V = 1/3 pi ( 2r)^2 (1/2 h)
V = 1/3 pi (4r^2) (1/2h)
V = 1/3 pi 2r^2 h
The volume of Cone B is twice the volume of Cone A.
