D. 133.45
Step-by-step explanation:
The formula for surface are of a cylinder is
SA = 2πr² + 2πrh where r is the radius of the base, and h is the height
We are given r = 2.5 and h = 6, plug those values in and evaluate
SA = 2π(2.5²) + 2π(2.5)(6)
SA = 12.5π + 30π
SA = 42.5π
**I'm assuming they are saying to use 3.14 as an approximation for π, so we have..
SA = 42.5(3.14) = 133.45
