To find the radius of the cone with a height of 12 and a base length of 8, we can use the properties of right triangles formed by the radius, height, and slant height (side) of the cone.
Given:
- Height (h) = 12
- Base length (diameter, d) = 8
First, we need to find the radius (r) of the base:
- Radius (r) = diameter / 2 = 8 / 2 = 4
So, the radius of the cone is 4.
Therefore, the correct answer is 04.
