Question:
What is the central angle of the sector (in the above pie chart) representing skin and bones together?
(a) 36o
(b) 60o
(c) 90o
(d) 96o
Solution:
(d) 96o
Distribution of protein in the skin = 1/10
Distribution of protein in the bones = 1/6
Central angle of the sector representing skin and bones,
= 1/10 + 1/6
= (3 + 5)/30
= 8/30 × 360o
= 96o
