In the app below, the 2D figure you see on the left is the same as the 2D figure you see on the right.
What is the height of your cone above? What is the radius of its base?
The 2D figure on the left is called a [i]cross section[/i] of the surface on the right. How is the cross section of this cone similar to the cross section of the cylinder (that you made in the previous activity)? How are these cross sections different? Explain.
