How Do You Calculate The Size Of A Round Pen?
To figure out the size of a round pen, you want to figure out the volume of the pen. A normal pen has two components, the tip and the round chamber that stores the ink. Therefore, to figure out the size of the pen, you need to calculate the volume of a cone, for the tip, and the volume of a cylinder, for the ink chamber. Adding these together tells you the size of the pen. Measure from the tip of the pen to where the chamber starts. For example, the pen tips height is 0.25 inches. Measure the length of the chamber. In the example, the pen’s chamber is 5 inches. Measure the diameter of the pen at the base of the pen. In the example, the base measure 0.2 inches. Divide this number in half to find the radius, so the radius equals 0.1 inches. Square the radius of the base, then multiply by 3.14. Multiply the result by 1/3 and then base the height of the tip. This is the volume of the tip. In the example, 0.1 squares equals 0.01. Then, 0.01 times 3.14 equals 0.0314. Next, 0.0314 times 1/3 i
