A sphere is 2/3 the volume of a cylinder … with the same diameter and height. A cone is 1/3 the volume of a cylinder… with the same diameter and vertical height.

Diameter of 3 in. V = (3.14) (r) (r) (h) A sphere is 2/3 the volume of a cylinder with the same diameter and height. Cylinder Sphere V = V = (volume of cylinder) Skip #3 - 4

A cone is 1/3 the volume of a cylinder… with the same diameter and vertical height. V =

What patterns do you see in how the volume grows as the radius increases? When the radius is doubled, how does the volume increase? How is the effect of scaling up the radius similar to the patterns you noticed when you scaled up rectangular prisms? The volume increases very rapidly as radius increases. When the radius is doubled, the volume increases by a factor of 8! When the radius is tripled, the volume increase by a factor of 27!

V = 64 cubic in. V = 42 and 2/3 cubic in. V = 21 and 1/3 cubic in. V =
