Geometry Concepts and Problem Solving

The video tutorial explains how to find the slant height of a cone using the Pythagorean theorem. It begins by introducing the concept of a cone and its slant height, then identifies a right triangle within the cone. The tutorial demonstrates how to apply the Pythagorean theorem to calculate the slant height, providing a step-by-step guide to the calculation process. The video concludes with finalizing the calculation and rounding the result.

What is the slant height of a cone?

• The length from the apex to any point on the base edge
