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.

113 cm²

Step-by-step explanation:

Given:

Diameter of the cone (d) = 8 cm

Slant height of cone (l) = 5 cm

The value of pi is approximated,

We know that, radius of half of diameter.

Radius = Diameter ÷ 2 = 8 ÷ 2 = 4 cm

Now, total surface area of a cone is given as:

Plug in the given values and solve for surface area, 'SA'. This gives,

Therefore, the total surface area of the cone is approximately 113 square centimeters.
