Acircle is drawn within a square as shown. what is the best approximation for the area of the shaded region? use 3.14 to approximate pi. 10.54 cm² 27.02 cm² 87.47 cm² 104.86 cm² circle inscribed inside a square with outside shaded, one side labeled 7 cm

The best approximation for the area of the shaded region is

Step-by-step explanation:

we know that

The area of the shaded region is equal to the area of the square minus the area of the circle

Step 1

Find the area of the square

The area of the square is equal to

where

b is the length side of the square

we have

substitute

Step 2

Find the area of circle

The area of the circle is equal to

we have

-----> the radius is half the diameter

substitute

Step 3

Find the area of the shaded region
