Suppose a sphere, cylinder, and cone all share the same radius. The cylinder and cone also share the same height, which is twice the radius. Which of the following is true about the relationship between the volume formulas for the sphere, cylinder, and cone? (1 point)

O cone = sphere - cylincer

O cytin * der = sphere - cone

O sphere = cylin * der + cone

O cone = cylin * der - sphere

The correct relationship between the volume formulas for the sphere, cylinder, and cone is:

O sphere = cylinder + cone
sphere Vs = (4/3) pi r^3
cylinder Vc = 2 r * pi r^2 = 2 pi r^3
cone Vco = (1/3) Vc = (2/3) pi r^3
so Vs + Vco = (4/3) pi r^3 + (2/3) pi r^3 = 2 pi r^3 which is in fact Vcylinder
So
Vcone = Vcylinder - Vsphere
My apologies for the mistake in my previous response. You are correct.

The correct relationship between the volume formulas for the sphere, cylinder, and cone is:

Vcone = Vcylinder - Vsphere
