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 t

Darina [25.2K]

Answer:

Option A and Option C

Step-by-step explanation:

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

$SA=\pi r^2+\pi rs$ (This matches with the option A)

Where $\pi rl$ is the lateral area of the cone (Being "s" the slant height) and $\pi r^2$ 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:

$SA=BA+LA$

This matches with the option C
