The total surface area of the given cone is

Step-by-step explanation:

Step 1:-

Formula:-

The total surface area of cone is

........(1)

Step 2:-

Given slant height

and radius of the circle (base) = 2

substituting these values in equation (1)

on simplification, we get

Final answer :-

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
