Explanation:

The total surface area of a cylinder includes the area of the two circular bases and the lateral (curved) surface area. The area of one circular base is $\pi r^2$, so two bases have an area of $2\pi r^2$. The lateral surface area is the circumference of the base times the height of the cylinder, which is $2\pi r h$. Adding these together gives the total surface area.

Answer:

The formula for the total surface area of a cylinder is $2\pi r^2 + 2\pi r h$ (or factored as $2\pi r(r + h)$), where $r$ is the radius of the circular base and $h$ is the height of the cylinder.
