To find the surface area of a cone, we use the formula:
Surface area = π * r * (r + √(r^2 + h^2))
Given that the diameter of the cone (d) is 25 cm, we can find the radius (r):
r = d/2
r = 25/2
r = 12.5 cm
We also need the height (h) of the cone to calculate the surface area. However, the height is not given in the question. Without the height, it is not possible to calculate the surface area. Therefore, the answer cannot be determined with the information given.
