The radius is 7 if the diam. is 14. We can find the surface area (without top or bottom areas) by finding the circumference of the base and then multiplying it by the height:
C=pi*d = pi(14); height = 9. Then the surface area of the side(s) is 14(pi)(9).
If you wish to include the areas of the top and bottom of the cylinder, add
2(pi)r^2 = 2(pi)(7)^2.
The answer would be A. 6.50. This is because 2.52 would be about 2.50 and 4.03 would be about 4 and 2.50 + 4 = 6.50
I would have to say that it is the 3rd answer choice due to the right angle that is formed between line C and line A.
