What is the surface area of the cone use 3.14 for pi 25 cm and 22 cm

Answer 1

To find the surface area of a cone, you need the slant height (l) and the radius (r).

Given the radius of 22 cm, we can calculate the slant height as follows:
l = √(22^2 + 25^2)
l = √(484 + 625)
l = √1109
l ≈ 33.306

Now, let's calculate the surface area of the cone:
Surface area = π * r * (r + l)
Surface area = 3.14 * 22 * (22 + 33.306)
Surface area = 3.14 * 22 * 55.306
Surface area ≈ 3871.546 cm²

Therefore, the surface area of the cone is approximately 3871.546 cm².
