The formula for finding the surface area of a cone using the slant height is:
SA = pi r l + pi r^2
where SA stands for surface area, r stands for radius, and l stands for slant height
Therefore, we can simply plug in all of the given values into the formula to get our answer.
The equation we would solve would be:
SA = 3.1445+3.144^2
This gives us 113.04
The answer that is closest to this would be 113
Therefore, the answer is 113
Hope this helped!!C:D
