Question

In the fig., AOBCA represents
the quadrant of a circle of
radius 3.5 cm. Calculate the
area of shaded portion. (Take
i = 22/7)​

Answer 1

Answer:

Area=12.25π /4 - √24.4

Step-by-step explanation:

Area of the Sector = 90/360 × πr^2

1/4 × πr^2 = 12.25π /4

so the area of shaded portion = 12.25π /4 - √24.4
