Part A:
The lateral surface area of a cylinder is given by the formula:
Lateral Surface Area = 2 * pi * radius * height
Plugging in the given values:
Lateral Surface Area = 2 * 3.14 * 4 * 5.5
Lateral Surface Area = 122.08 m^2 (rounded to the nearest hundredth)
Part B:
The total surface area of a cylinder is given by the formula:
Total Surface Area = 2 * pi * radius * (radius + height)
Plugging in the given values:
Total Surface Area = 2 * 3.14 * 4 * (4 + 5.5)
Total Surface Area = 138.16 m^2 (rounded to the nearest hundredth)
Therefore, the correct answer is:
138.16 m^2
