## Move the net extend slider to find the shapes that create a cone.

What shapes create a cone?

**Use the following applets to figure out the relationship between the volume of a cylinder and the volume of a cone.**

## The sliders control the radius and height of the cylinder and cone below. Adjust the sliders.

## Use the sliders to change the radius (r) and height (h) of the cylinder and the cone. What is the relationship between the volumes of the cylinder and the cone when they have the same radius and height measurements?

## Transfer the water being held in the cone to the cylinder, the water fills how much of the cyliner?

What is the relationship of the volume of the cylinder and the cone?

A city zoo builds an enclosure for birds in the shape of a cone with the dimensions shown. There are 42 birds contained in the enclosure.
What is the volume of the enclosure to the nearest whole number?
