The cone shown has a diameter of 8 centimeters and a slant height of 5 centimeters. Which choice is closest to the total surface area? Use 3.14 to approximate pi.

63 square centimeters


113 square centimeters


126 square centimeters


327 square centimeters

the answer is 113 because the height and cenimeters are added and they are divided and it equals to 113

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 = 3.14*4*5+3.14*4^2

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
