Part A:
The lateral surface area of a cylinder is given by the formula 2πrh, where r is the radius and h is the height.
Plugging in the given values, we have: 2 * 3.14 * 4 * 5.5 = 138.16 m^2.
So, the lateral surface area of the cylinder is 138.16 m^2.
Part B:
The total surface area of a cylinder is given by the formula 2πr(r+h), where r is the radius and h is the height.
Plugging in the given values, we have: 2 * 3.14 * 4 * (4+5.5) = 238.64 m^2.
So, the total surface area of the cylinder is 238.64 m^2.
