Foundation November 2024 Paper 2 Q28
28 The diagram shows a solid cylinder with base radius 3 cm and height 10 cm.
The cylinder is made from steel.
It has a mass of 2250 g.
Work out the density of the steel.
Give your answer correct to 3 significant figures. (3)
| Answer | Mark | Mark scheme |
|---|---|---|
| 7.96 | M1 | for method to find volume of cylinder, eg \(\pi \times 3^2 \times 10\ (= 90\pi\) or \(282.74\ldots)\) |
| M1 | for method to find density, eg \(2250 \div \text{``}282.74\ldots\text{''}\) or \(2250 \div [\text{volume}]\) | |
| A1 | for answer in the range 7.95 to 7.96 |
Additional guidance
[volume] is any value they clearly think is the volume of the cylinder but must come from a calculation and must not be 3 or 10
