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.

Area of the square:
A ( square ) = 10² = 100
Area of the circle:
A ( circle ) = 5² π = 25 · 3.14 = 78.5
Area of the shaded region:
A = 100 - 78.5 = 21.5

A ) 21.5 cm² 

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
