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.A.2r2 + 2rhB.BA + LAC.BA + 2r2D.2LA + r2E.r2 + rs

The correct formulas for finding the surface area of a right cone are:

B. BA + LA E. r^2 + rs

Here's why:

B. BA + LA: The surface area of a cone is the sum of the base area (BA) and the lateral area (LA).

E. r^2 + rs: This is another way to express the surface area of a cone. r^2 represents the base area (which is a circle, so the area is πr^2, but often π is omitted in these types of problems), and rs represents the lateral area (which is a sector of a circle, so the area is 1/2 the circumference times the slant height, or πrs, but again, π is often omitted).

The other options are incorrect:

A. 2r^2 + 2rh: This formula is incorrect. It seems to be a mix of the formulas for the volume of a cylinder (πr^2h) and the surface area of a sphere (4πr^2).

C. BA + 2r^2: This formula is incorrect. It seems to be adding an extra base area to the correct formula.

D. 2LA + r^2: This formula is incorrect. It seems to be doubling the lateral area and adding it to the base area.
