Question

find the shaded area if diameter of the circle is 14cm, AC = BC​

Answer 1

Answer : Area of shaded region = 91cm²

Step-by-step explaination :

$area \: \: of \: \: triangle \: \: = \frac{1}{2} \times b \times h$

$= \frac{1}{2} \times 14 \times 7$

$= 7 \times 7$

$= 49 {cm}^{2}$

$area \: \: of \: \: circle = \pi {r}^{2}$

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

$= 22 \times 7$

$= 154 {cm}^{2}$

$area \: \: of \: \: square \: = {(side)}^{2}$

$= {(14)}^{2}$

$= 196 {cm}^{2}$

$area \: \: of \: \: shaded \: \: region = area \: \: of \: \: square \: - area \: \: of \: circle \: + area \: \: of \: \: triangle$

$= 196 - 154 + 49$

$= 91 {cm}^{2}$
