To find the total surface area of the cylinder, we need to calculate the areas of the two circles at the top and bottom, as well as the curved surface area.
The formula for the area of each circle is A = πr^2, where r is the radius.
Area of the top circle = π(2.5^2) = 19.63 m^2
Area of the bottom circle = π(2.5^2) = 19.63 m^2
The formula for the curved surface area of a cylinder is A = 2πrh, where r is the radius and h is the height.
Curved surface area = 2π(2.5)(7) = 109.96 m^2
Now we can calculate the total surface area by adding the areas of the circles and the curved surface area:
Total surface area = Area of top circle + Area of bottom circle + Curved surface area
Total surface area = 19.63 + 19.63 + 109.96
Total surface area = 149.22 m^2
Therefore, the correct answer is 149.22 m^2.
