What is the formula to find the dimension of a cylinder?

To find the dimensions of a cylinder, you need its radius (r) and height (h). The formula for the volume (V) of a cylinder is ( V = \pi r^2 h ), where ( \pi ) is approximately 3.14. The surface area (A) of a cylinder can be calculated using the formula ( A = 2\pi r(h + r) ). These formulas provide the necessary relationships to derive the dimensions based on given volume or surface area.
