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
