Calculate the dimensions for a cone and frustum template.

Here are the calculations for the cone and frustum templates based on the provided dimensions.

Part 1: Cone Template
The diagram shows a cone with a base radius of $10 \text{ cm}$ and a height of $20 \text{ cm}$.

Step 1: Calculate the slant height ($L$) of the cone.
The slant height is the hypotenuse of a right triangle formed by the radius and the height.

$$L = \sqrt{r^2 + h^2}$$ $$L = \sqrt{(10 \text{ cm})^2 + (20 \text{ cm})^2}$$ $$$$
