How long mm diameter cylinder to hold ml?

To determine the length of a cylinder required to hold a specific volume in milliliters (ml), you can use the formula for the volume of a cylinder: ( V = \pi r^2 h ), where ( V ) is the volume, ( r ) is the radius, and ( h ) is the height (or length). First, convert the diameter in millimeters (mm) to radius in millimeters by dividing by two. Then, rearrange the formula to solve for the height ( h ) using the desired volume in ml (1 ml = 1 cm³).
