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:-

As here length an width both are 11 cm, we can say that this is a square.

                          =

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
