What is the formula for cylinder

• The formula for the volume of a cylinder is:

$$V = \pi r^2 h$$

where $r$ is the radius of the base and $h$ is the height of the cylinder.

• The formula for the total surface area of a cylinder is:

$$SA = 2 \pi r^2 + 2 \pi r h$$

where $r$ is the radius of the base and $h$ is the height of the cylinder. The $2 \pi r^2$ part represents the area of the two circular bases, and $2 \pi r h$ represents the area of the curved side.
