Answer:
The surface area of the cone is 395.64 cm²
Step-by-step explanation:
The surface area of a cone in terms of radius and slant height is:
A = πr² + πrs, where r is the radius and s is the slant height.
As can be seen, the given radius is 7 cm and the slant height is 11 cm; substitute:
A = π(7²) + π(7)(11)
A = 49π + 77π
Putting π = 3.14,
A = 49(3.14) + 77(3.14)
A = 153.86 + 241.78 = 395.64 cm²
