Question

Area of a sector of angle $P^o$ of a circle with radius $R$ is

Answer 1

Area of a sector $=\frac{\theta }{360}\times \pi r^2$

where $\theta =$angle , $r=$ radius

Here we have

$\theta =P$ and radius$=R$

Pitting the values in formula

Area of sectors $=\frac{\theta }{360}\times \pi R^2$

$=\frac{P}{360}\times \pi R^2$

Let us multiply the $2$ in numerator and denominators

$=\frac{P}{360}\times \pi R^2\times \frac{2}{2}$

$=\frac{P}{720}\times 2\pi R^2$
