  • Tick the correct answer in the following : Area of a sector of angle p (in degrees) of a circle with radius R is (A) p / 180 x 2 pi R (B) p / 180 x pi R ^2 (C) p / 360 x 2 pi R (D) p / 720 x 2 pi R ^2

14.    Tick the correct answer in the following :

Area of a sector of angle p (in degrees) of a circle with radius R is

                (A)    \frac{p}{180}\times 2\pi R

                (B)    \frac{p}{180}\times \pi R^2

                (C)    \frac{p}{360}\times 2\pi R

                (D)    \frac{p}{720}\times 2\pi R^2

We know that the area of the sector is given by:-

                                                    Area\ =\ \frac{\Theta}{360^{\circ}}\ \times \pi r^2

                                                               =\ \frac{p}{360^{\circ}}\ \times \pi r^2

Hence option (d) is correct.
