1.	The following pie chart represents the distribution of proteins in parts of human body.What is the central angle of the sector representing hormones enzymes and other proteins?(a) 120° (b) 144° (c) 156° (d) 176°
Answer» (b) 144^o Distribution of protein in the skin = 1/10 Distribution of protein in the bones = 1/6 Distribution of protein in the Muscles = 1/3 Central angle of the sector representing skin, muscles and bones, = 1/10 + 1/6 + 1/3 = (3 + 5 + 10)/30 = 18/30 × 360^o = 216^o Then, Central angle of the sector representing hormones enzymes and other proteins, = 360^o – 216^o = 144^o

The following pie chart represents the distribution of proteins in parts of human body.What is the central angle of the sector representing hormones enzymes and other proteins?(a) 120° (b) 144° (c) 156° (d) 176°

Answer»

(b) 144^o

Distribution of protein in the skin = 1/10

Distribution of protein in the bones = 1/6

Distribution of protein in the Muscles = 1/3

Central angle of the sector representing skin, muscles and bones,

= 1/10 + 1/6 + 1/3

= (3 + 5 + 10)/30

= 18/30 × 360^o

= 216^o

Then,

Central angle of the sector representing hormones enzymes and other proteins,

= 360^o – 216^o

= 144^o
