A
A = pi * r2 ✔✖
B
A = pi * r * h ✔✖
C
A = pi * r2 + pi * r * h ✔✖
D
A = pi * r * (r + h) ✔✖
D
Correct Answer: D
Explanation
The formula for the surface area of a cone is A = pi * r * (r + h), where r is the radius of the base and h is the height of the cone. The term pi * r * (r + h) represents the lateral surface area of the cone, which is the area of a sector of the base multiplied by the slant height of the cone.
