Question

A survey of 200 people found that 20 of them played chess . In a pie chart , what would be the sector angle of this group?

Answer 1

`36^0`

Explanation:

Since the % of people is 10. [ Out of 200 people 20 people played Chess so percentage of people played chess will be 10]
Since angle of Circle is `360^0`
Hence 10 % of 360 will be 36
so,
`angle/360 = 10/100`
or
`angle=360*10/100`
or
`angle=3600/100`
or
`angle=36/1`

Hence Sector angle is = `36^0`
