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. 21.5 cm² 78.5 cm² 100 cm² 178.5 cm² circle inscribed inside a square with outside shaded, one side labeled 10 cm

To answer this question you will need to find the area of the square, and subtract the area of the circle from it. To find the area of the square you will multiply the length by the width In this case it would be 10×10 = 100 cm². To find the area Of the circle you would use the formula A =equals Pi times the radius squared. Since the diameter of the circle is 10 cm, the radius would be 5 cm. This would be 3.14×5 squared. The value of this is 78.5 cm². 100 cm² -78.5 cm² equals 21.5 cm² which is the answer.
