Question 93

Find the area of the shaded portion in the given figure.

Answer 1

Area of shaded portion = Area of circle - Area of square $=\pi r^2-4\times$ Area of $\Delta AOB$

= $\frac{22}{7}\times 7\times 7-4\times (\frac{1}{2}\times AO\times BO)$

= $\frac{22}{7}\times 7\times 7-2\times 7\times 7$

= 154 - 98 = 56 $c{m}^2$
