Ex 4.1, 2 (ii) Find the central angle of each sector. Total Votes = 90 + 120 + 150 = 360 Fraction = (𝑵𝒖𝒎𝒃𝒆𝒓 𝒐𝒇 𝑽𝒐𝒕𝒆𝒔)/(𝑻𝒐𝒕𝒂𝒍 𝑽𝒐𝒕𝒆𝒔) ∴ Central angle of summer = 90° Central angle of rainy = 120° Central angle of winter = 150° We follow the steps 1. Draw a circle of any radius. Mark Radius as OA. 2. Put protractor on AO and Draw largest angle 150° 3. Now, put protractor on AO and Mark angle 90° 4. The remaining portion is 120° 5. Now, Label the pie chart
