To Find : Draw Pie Chart
Solution:
A pie chart (or a circle chart) is a circular statistical graphic, which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice (and consequently its central angle and area), is proportional to the quantity it represents.
144 will be 360° ( Complete Circle)
Red 12 = (12/144) * 360° = 30°
Yellow 18 = (18/144) * 360° = 45°
Blue 28 = (28/144) * 360° = 70°
Green 42 = (42/144) * 360° = 105°
White 44 = (44/144) * 360° = 110°
using this angle pie chart can be Drawn
