Volume of a cone

Let’s explore cones
and their volume.

Today’s Goals

❏ I can find the volume of a cone in mathematical and

real-world situations.

❏ I know the formula for the volume of a cone.

Now it's time for you to practice.

Practice

Organize: Lesson 15 Synthesis

●What is the relationship between the volume of a cylinder and the volume
of a cone?

●If we know the volume of a cone, how do we calculate the volume of a
cylinder that has the same height and base area?

●If we know the volume of a cylinder, how do we calculate the volume of a
cone that has the same height and base area?

●If a cylinder and a cone have the same base, how tall does the cone have
to be relative to the cylinder so that they both have the same volume?
