Question

What is the area of The shaded sector of the circle

Answer 1

area of circle = pi r^2 = 81pi

1/3 of circle = 81pi / 3 = 27 pi units^2

answer
B. 27 pi units^2

Answer 2

Answer: 27
`\pi`
`unit^(2)`

Step-by-step explanation: area of circle =
`\pi  r^(2)`

where r is the radius of circle

here r=9

to find the area of circle we cover an angle of 360° but here we have to cover only 120°=360°÷3

so area of shaded region =area of circle÷3

=
`\pi`×9×9÷3

=27
`\pi`
`unit^(2)`
