Question 27
A student uses a cup of water to measure volume of an irregular screw. The diameter of the cup is 4 cm. The height of the water surface for several screws is measured using a ruler. The data is shown in the table below:
| Number of screws | Height of water surface (cm) |
| --- | --- |
| 0 | 5.00 |
| 5 | 7.45 |
| 15 | 12.30 |
| 25 | 17.00 |
| 35 | 21.85 |
Explain how you can find the volume of a screw. Estimate the volume of one single screw.
