The formula for surface area of a cylinder:
S.A. = 2πrh + 2πr², where r is the radius and h is the height.
The radius and height are given as follows:
r = 8
h = 16
Plug them into the above formula and solve.
S.A. = 2πrh + 2πr²
S.A. = 2π(8)(16) + 2π(8)²
S.A. = 256π + 2π64
S.A. = 256π + 128n
S.A. = 384π or approx. 1206
