Question

In the following figure, the radius of the circle is $7$ cm and $m\left(arcRYS\right)={30}^{\circ }$, find find:
Area of the circle

Answer 1

In the given figure,
Radius of the circle with centre $P$ is $r=7$ cm
$M\left(arcRYS\right)={30}^{\circ }$
Area of circle $=\pi r^2$
$=\frac{22}{7}\times 7\times 7$
$=154c{m}^2$
