as shown in the figure below. Which of the following expressions would help
him find the area of the shaded sector?

90

B.

C.
270 (67)
350

D.
90
- (127)

Answer 1

B. 90/360, because this is 1/4 from circle. It's even shown in the picture.
Example: If you take a protractor at 180°, then if you mirror it, then 360° will comeout, i.e. a circle.
