Question

Radius of a sector of a circle is 7 cm. If measure of arc of the sector is -
(1) 30°  find the area of the sector 

Solution

Radius of the sector of the circle, r = 7 cm
(1) Measure of arc of the sector = θ = 30º
∴ Area of the sector = \[\frac{\theta}{360°} \times \pi r^2 = \frac{30°}{360°} \times \frac{22}{7} \times \left( 7 \right)^2\]  = 12.83 cm
