Answer:
A. 68 units2
Step-by-step explanation:
First of all to solve this problem we have to know the formula to calculate the surface area of the cone
A = area
r = radius = 4
L = 13
π = pi
A = π*r² + π*L*r
we replace with the known values
A = π * (4u)² + π * 13u * 4u
A = 16π u² + 52π u²
A = 68π u²
The surface area of the cone is 68π u²
