In preparing rice cutlets, a cook used 75g of rice, 40g of margarine, 105g of meat and 20g of bread crumbs. Find the angle of the sector which represents meat in pie chart
30o
60o
112.5o
157.5o
Explanation
Rice = 75g, Margarine = 40g, Meat = 105g, Bread = 20g, Total = 240
Angle of sector represented by meat
= \(\frac{105}{240}\) x \(\frac{360°}{1}\) = 157.5°
Angle of sector represented by meat
= \(\frac{105}{240}\) x \(\frac{360°}{1}\) = 157.5°
