🔍 Key Concepts

• Use the cylinder volume formula for a round cylinder: (V = \frac{\pi D^2}{4} \times \text{stroke}). • Identify the bore (diameter) and stroke values from illustration MO-0004. • Keep track of units – everything in this problem is in inches and the answer choices are in cubic inches.

💭 Think About

• From the data sheet, which two numbers correspond to the bore (cylinder diameter) and the stroke (piston travel)? • After you compute the geometric volume of one cylinder, does it seem reasonable compared with the total displacement given on the sheet? • If you divide the total displacement by the number of cylinders shown, do you get essentially the same value you calculated from the bore and stroke?

✅ Before You Answer

• Be sure you square the bore (diameter), not the radius, before multiplying by (\frac{\pi}{4}). • Confirm that the stroke you use is in the same units (inches) as the bore so the final result is in cubic inches. • Double-check that your per‑cylinder volume, when multiplied by the number of cylinders, matches the listed total displacement within rounding error.
