Cylinders, Cones, Pyramids and Spheres

3. Cylinder
Volume = r2h
See homework examples

4. Real Life Cylinders

5. Cones

6. Cones

7. Cones Pringles A third of the calories A fact:
If Pringles came in a cone, which was the same height and diameter as the tall tube, it would contain one third of the calories!!!
Why??
Pringles
A third
of the
calories

8. Cones
Volume =
Slant height (l)
Example: find the volume of this cone
