The formula for the surface area of a cone is:
Surface Area = πr^2 + πrL
Where r is the radius of the base of the cone and L is the slant height of the cone.
Given that the diameter (d) of the base of the cone is 25 cm, the radius (r) can be calculated as half of the diameter:
r = d/2 = 25 cm / 2 = 12.5 cm
The slant height (L) can be calculated using the Pythagorean theorem, where L is the hypotenuse of a right triangle formed by the radius and the height (h) of the cone:
L = √(h^2 + r^2)
Since the height (h) is not given in the question, it is not possible to determine the exact surface area of the cone.
