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
Answer:
8/10
Step-by-step explanation:
8/10 = 80/100 > 63/100
20x+5y = -16
Take the 20x to the other side to get.
5y = -20x -16
Then divide both sides by 6.
So y = -4x -3
