Question

find the area of the shaded region??​

Answer 1

Answer:

Area of a sector = (θ / 2) × r2 where r = radius and θ is in radians.

or Area of a sector = (θ / 360) × πr2 where θ is in degrees.

Step-by-step explanation:

So, we use the formula A = (θ / 2) × r2 or (θ / 360) × πr2 is used to find the area of the sector of the circle.

Answer 2

Step by Step Answer:-
1. Find the length of diagonal of a rectangle and find out area of rectangle.
2. Length of diagonal gives the length of diameter of a circle.
3. Then by using radius find area of circle.
4. And finally to find the area of the shaded region subtract area of rectangle from area of circle.
