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
This is a pretty large figure, so let us break it into pieces.
-> See attached for how I broke it up and for how I solved
-> The area of a rectangle can be found from doing lengths times width equals area
Things I forgot to clarify in my image:
-> The 4 comes from 10 - 6 = 4
-> The 6 comes from 9 - 3 = 6
