Ps. This one can't show working because this one needs to use protractor. *Accurately* implies that is drawn to scale and therefore you must use protractor.
Prior knowledge
-One full circle is 360 degree.
-Use protractor to measure the angle of RED section
- Divide 360 by the angle of RED
- Take the answer multiple by 48. Then round off to the nearest number. E.g. you get 32.8 ~ round it off to 33. Because students cannot have decimal. It must be whole number .
