A. Area
To find the surface area of a cylinder, we need to calculate the areas of the two circular bases and the lateral surface area of the cylinder.
1. The area of the circular base can be calculated using the formula for the area of a circle, which is πr^2.
2. Since a cylinder has two circular bases, we need to calculate the total area of both bases by multiplying the area of one base by 2.
3. The lateral surface area of a cylinder can be found by calculating the circumference of one of the circular bases (2πr) and multiplying it by the height of the cylinder (h).
4. Add the areas of the two bases and the lateral surface area to find the total surface area of the cylinder.
Therefore, the formula for the area of a cylinder is:
Total Surface Area = 2(πr^2) + 2πrh
