Question
Find the lateral area of this cone.
- 130π ft.2
Hint:
The Formula lateral surface area of the cone is 
where l is the slant height and r is the radius of the circular base of the cone.
The correct answer is:
Given radius r = 5 ft and height h = 12 ft and using formula for slant height
Therefore, The lateral surface area of the cone is .

Identify the shape that will be angled cross-section of a rectangular pyramid.
The plane cuts the pyramid at an angle which is not parallel to the base of the cone, this is the reason why we are getting a rectangle but with a length : breadth ratio different than that of the base.

Name the shape that would result from slicing a rectangular pyramid parallel to the base
Since the pyramid is rectangular, this means that the base of the pyramid is a rectangle. Therefore, if we slice it parallel to the base, we’ll get a cross section which will look like the base of the pyramid, i.e., a rectangle.
