Answer:
42.43
Step-by-step explanation:
Given:
A circle with a radius of 5 cm sits inside a 11 cm x 11 cm rectangle.
Question asked:
What is the area of the shaded region as shown in the figure ?
Solution:
First of all calculate area of circle and then area of rectangle:-
<u>As here length an width both are 11 cm, we can say that this is a square.</u>
<u />
Now, area of shaded region = Area of square - Area of circle
= 121 - 78.571 = 42.429
Therefore, the area of the shaded region will be 42.43
