The surface area (SA) of a cone is given by the formula SA = πr(r + l) where r is the radius and l is the slant height.

Given that the radius (r) is 2 units and the slant height (l) is 6 units, we can substitute these values into the formula:

SA = π * 2 * (2 + 6)
SA = π * 2 * 8
SA = 16π units^2

The value of π (Pi) is approximately 3.14, so the surface area is approximately 16 * 3.14 = 50.24 units^2.

However, this answer is not in the options. It seems there might be a mistake in the question or the answer choices. The correct answer should be approximately 50.24 units^2.
