Which of the following formulas would find the surface area of a right cone where s is the slant height r is the radius, la is the lateral area, and ba is the base area?

check all that apply.

Option A and Option C

Step-by-step explanation:

The surface area of a cone can be calculated with this formula:

(This matches with the option A)

Where is the lateral area of the cone (Being "s" the slant height) and is the area of the base of the cone (which is a circle).

You know that BA the is the area of the base and LA the lateral area of the cone.

Then, substituting into the formula for calculate the surface area of a cone, you get:

This matches with the option C

step-by-step explanation:

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
