Question

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

Answer 1

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

Answer 2

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
