Question

2. Now that you have the height of the cone, how can you solve for the
slant height, s?

Answer 1

s^2 = r^2 + h^2.

Explanation:

You need to know the radius of the base as well.

Then you use the Pythagoras theorem:

s^2 = r^2 + h^2 where r = radius and h = the height.

Answer 2

Use the formula: square root( r^2 +h^2)
