Question

A circle 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

Answer 1

Diameter of the circle is 10cm
so radius is 10/2= 5cm

Now coming to the area of the circle which is pi r2
                                                                       = (3.14* 5 *5) cm2
                                                                       =78.5cm2
