    Choice b is correct answer.

    Step-by-step explanation:

    From question statement, we observe that

    Radius and height of the cylinder is given.

    Radius = r = 38 mm and height = h = 51 mm

    We use the following formula to find surface area.

    A = 2πrh+2πr² where r and h denotes radius and height of cylinder respectively.

    Putting given values in above formula, we get

    A = 2π (38) (51) + 2π (38) ²

    A = 3876π + 2888π

    A = 6764π mm²

    Hence, the area of cylinder is 6764π mm².
