Question
What is the central angle of the sector representing skin and bones together?
Options
36°
60°
90°
96°
Solution
96°
Explanation:
Total protein in bones and skin = `1/6 + 1/10`
= `(3 + 5)/30`
= `8/30`
∴ Central angle of skin and bones = `8/30 xx 360^circ`
Central angle of the sector showing skin and bones together = 96°.
