The pie chart given below shows the number of tyres of 6 companies. Number of tyres of a particular company are shown as a percentage of total number of tyres of these 6 companies. What is the sum of central angles formed by the sectors representing tyres of company F and A ?
144 degrees
Given:
A% = 12%
F% = 28%
Formula used:
360° = 100%
Solution:
1% = 3.6 °
Now, the sum of central angle formed by A & F = 12% + 28% = 40%
40% = 40 x 3.6° = 144°
Hence, the sum of central angles formed by the sectors representing tyres of Company F and A is 144 degrees.
