Drawing a pie chartSuppose we are given data like We convert Percentage → Angles We know that Angle at center = 360° So, we convert So, our table becomes. We follow the steps 1. Draw a circle of any radius. Mark Radius as OA. 2. Put protractor on AO and Draw largest angle 144° 3. Now, put protractor on AO and Mark next largest angle 90° 4. Now, put protractor on OC and Mark next largest angle 72° 5. The remaining portion is 54° 6. Now, label the pie chart Let’s take another example We are given the type of movie that students of class VIII like are Draw a pie chart of the same Suppose we are given data in following from Now to make pie chart we have find angles We follow these steps 1. Draw a circle of any radius. Mark Radius as OA. 2. Put protractor on OA and Draw largest angle i.e 180° 3. Now, put protector on OB, and draw the next largest angle i.e 90° 4. Put protractor on OC and mark next largest angle i.e 72° 5. The remaining portion is 18° 6. Now, Label the pie chart
