Step3 Convert the percentage to degrees of a circle by multiplying by 3.6. (100 per cent of the circle = 360 degrees, so 1 per cent of the circle = 3.6 degrees.)

Step4 Draw a straight line from the centre of the circle to 12 o’clock. Step5
Use the protractor to mark the ýrst and largest segment, working clockwise. To do this, place the 0 degrees line on the protractor along the line you have just drawn. Now mark in the second largest group. Use the protractor to mark each of the other segments in descending size, marking the ‘other’ category last (if needed).
