Vedclass · Answer

(B) The area of a full circle with radius $r$ is given by the formula $A = \pi r^2$.This area corresponds to a central angle of $360^{\circ}$.By the unitary method,the area of a sector with a central angle of $	heta$ degrees is proportional to the ratio of the angle $	heta$ to the total angle $360^{\circ}$.Therefore,$	ext{Area of sector} = \frac{	heta}{360^{\circ}} 	imes \pi r^2$.This simplifies to $\frac{\pi r^2 	heta}{360}$.

If $\theta$ is the angle (in degrees) of a sector of a circle of radius $r$,then the area of the sector is:
