Question
A circle is inscribed in square ABCD of side 14 cm. Complete the following activity to find the area of the shaded portion.
Activity:
Area of square ABCD = ______
= 142
= 196 cm2
Area of circle = πr2 = `22/7xx 7^2`
= ____ cm2
Area of shaded portion = Area of square ABCD – Area of circle
= 196 – _______
= _____ cm2

Solution
Area of square ABCD = (side)2
= 142
= 196 cm2
Area of circle = πr2 = `22/7xx 7^2`
= 154cm2
Area of shaded portion = Area of square ABCD – Area of circle
= 196 – 154
= 42cm2
