What is the central angle of the sector (in the above pie chart) representing hormones enzymes and other proteins.
(a) 120°
(b) 144°
(c) 156°
(d) 176°
Solution:
Given the pie sector representing hormones , enzymes and other proteins is remaining angle of the pie
It is given as 1 - (1/10 + 1/6 + 1/3) = 1 - (0.1 + 0.5) = 0.4 = 2/5
The central angle is 2/5 × 360° = 144°
✦ Try This: What is the central angle of the sector (in the above pie chart) not representing hormones, enzymes and other proteins. (a) 120°, (b) 144°, (c) 156°, (d) 216°
Given the pie sector representing hormones , enzymes and other proteins is remaining angle of the pie
It is given as 1 - (1/10 + 1/6 + 1/3) = 1 - (0.1 + 0.5) = 0.4 = 2/5
The central angle is 2/5 × 360°= 144°
The angle not representing hormones and enzymes is given as 360° - 144°= 216°
