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


You didn't provide your units here, but be sure to include them in your answer!


Answer:

384π units² or approximately 1,206 units².
