Download free pie charts worksheets (PDF), GCSE maths past paper questions and worked solutions for Pie charts (2S). This is a Grade 2 statistics topic from the GCSE questions by topic collection for Foundation and Higher tier GCSE Maths (Edexcel, AQA, OCR and IGCSE).
All the angles at the centre of a pie chart add up to 360°. To draw a pie chart, divide 360° by the total frequency to find how many degrees represent 1 item (Multiplier = 360° ÷ Total), then multiply each frequency by that angle. Always check your angles add up to 360°.
To find a frequency from a given pie chart, write the sector angle as a fraction of 360° and multiply by the total number of people: Frequency = Angle360 × Total.
Example 1: Calculate the pie chart angles for 60 students.
