Question

can you say this answer anybody pls

Answer 1

Given that 3 sector of 40 degree each means 120 degree ( 3*40=120 )
And sum of angles of a circle is 360 degree so
Remaining area be x
Then
X + 120 = 360
X = 360 -120
X = 240
So remaining angle is 240 degree area is pi×r2 = 22/7×9
= 28 cm2 approx
