Question

Step 2: measure the area of the top of the syringe

Answer 1

I am unsure if this is correct, but this might be the whole section:

• The top of the syringe is a circle. You need to compute its area for use in later computations of pressure values. Start by using a ruler to measure the diameter. Estimate to the nearest 0.01 cm. Answer: 3.60 cm
• Divide by two to find the radius. Maintain significant figures. Answer: 1.80 cm
• Substitute the radius into the formula A = πr² to find the area of the top of the syringe. Maintain significant figures. Answer: 10.2 cm²
