The formula for the surface area of a cylinder is 2πr² + 2πrh, where r is the radius and h is the height.
Plugging in the values given, we get:
Surface Area = 2π(8²) + 2π(8)(20)
Surface Area = 128π + 320π
Surface Area = 448π
Therefore, the surface area of the cylinder in terms of pi is 448π in², which corresponds to (d) in the answer choices.
What is the surface area of the cylinder in terms of pi? the diagram is not drawn to scale.
