Answer:
Second option: Surface area = 176*pi cm2
Step-by-step explanation:
The surface area of a cylinder is given by:
S = 2*pi*r^2 + 2*pi*r*h
Where r is the base radius and h is the height.
If we have that the diameter is 8 centimeters, the radius is 8/2 = 4 centimeters. So with r = 4 and h = 18, we have that the surface area is:
S = 2*pi*4^2 + 2*pi*4*18 = 176*pi cm2
So the answer is the second option.
