Question

In a circle of radius 14 cm, an arc subtends an angle of

450 at the Centre, then find the area of the sector​

Answer 1

Answer:

Radius, r = 14 cm

Central angle, x = 45°

Area of sector is given by

$\pi \: {r}^{2} \frac{x}{360} \\ = \frac{22}{7} \times 14 \times 14 \times \frac{45}{360} \\ = 77 \: {cm}^{2}$

Answer 2

Answer:

$77 {cm}^{2}$
