These two cylinders are printed on a 3D printer, with a setting of 40% fill rate. This means that the solid parts of the cylinders are 40% plastic material. Given this information, how much plastic material is used to make each of these cylinders?

1. Methodology- This experiment is not as simple as measuring and using a formula. The cylinder is not solid in two respects: it is empty through its center, and the actual material is not itself solid as it is 40% filled. State the methodology - how the equations will be used to achieve the object of the lab (How much plastic material is used to make each of these cylinders?).
2. Data Collection- In order to complete the lab, research and data collection are needed.
   1. a) What is the equation for the volume of a cylinder?
   2. b) Define each variable used and the standard unit for each variable.
   3. c) To solve the equation, one of many possible tools from the kit is used to take certain

measurements. Which tool was chosen and why?

1. Data Analysis- Report the calculations done.
2. Conclusion- What was the volume of plastic used to print these cylinders?
3. BONUS QUESTION- One student says that he used the string and the equation for circumference to verify the outside radius. Then, he just measured the width of the ring and the height of the cylinder and had all the information he needed. How did he come to this conclusion?

My measurements are as follows( I measured in millimeters):

Tall cylinder:

Height:4mm

Inner Radius: 1.1mm

Outer Radius:1.5 mm

Small Cylinder:

Height:2mm

Inner Radius: 1mm

Outer Radius:1.6mm
