Question

a sphere,a cylinder and a cone have the same radius and same height.find the ratio of there volumes

Answer 1

sphere:cylinder:cone
is the ratio of there volumes

Answer 2

sphere | V = (4 pi r^3)/3
cylinder | V = pi r^2 h
cone | V = 1/3 pi r^2 h
where r is the radius and h is the height

assuming h != r
sphere to cylinder: ((4/3)r):(h)
cylinder to cone: 1:(1/3)
sphere to cone: 4r:h

assuming h = r
sphere to cylinder: (4/3):1
cylinder to cone: 1:(1/3)
sphere to cone: 4:1
