To find the total surface area of a cylinder, we need to find the lateral surface area and the area of the two bases and then add them together.
The formula for the lateral surface area of a cylinder is 2 * pi * r * h, where r is the radius and h is the height.
In this case, the radius is 2.5 meters and the height is 7 meters.
So the lateral surface area is 2 * 3.14 * 2.5 * 7 = 109.88 m2.
The formula for the area of the base of a cylinder is pi * r^2.
In this case, the radius is 2.5 meters.
So the area of the two bases is 2 * 3.14 * 2.5^2 = 39.25 m2.
Therefore, the total surface area of the cylinder is 109.88 + 39.25 = 149.13 m2.
So the correct answer is 149.15 m2.
What is the total surface area of the cylinder from Part A? (Radius is 2.5 meters and height is 7 meters).
Use 3.14 for pi.
