Solution

The surface area (SA) of a cone is calculated using the formula:

SA = πr(r + l)

where r is the radius and l is the slant height.

Given that the radius (r) is 4 units and the slant height (l) is 6 units, we can substitute these values into the formula:

SA = π * 4 * (4 + 6) SA = π * 4 * 10 SA = 40π

Therefore, none of the options A, B, C, or D is correct. The surface area of the cone is 40π square units.
