To find the surface area of an oblique cylinder, we need to calculate the lateral surface area and the area of the two bases.
The lateral surface area of a cylinder is given by the formula: Lateral Surface Area = 2πrh, where r is the radius and h is the height.
Given that the radius is 5 centimeters and the height is 15 centimeters, the lateral surface area is: 2 * 3.14 * 5 * 15 = 471 square centimeters.
The area of the two bases can be calculated using the formula: Base Area = πr^2, where r is the radius.
Given that the radius is 5 centimeters, the area of the two bases is: 2 * 3.14 * (5)^2 = 157 square centimeters.
The total surface area of the cylinder is the sum of the lateral surface area and the area of the two bases: Surface Area = Lateral Surface Area + Base Area = 471 + 157 = 628 square centimeters.
Therefore, the correct answer is 628 square centimeters.
