Q.2 (A)(3) The radius of a circle is 14 cm and the measure of the central angle of a sector is 45°. Complete the following activity to find the area of the sector and the length of its arc. \(\left(\pi = \dfrac{22}{7}\right)\)

Solution :

Area of sector \(= \dfrac{\theta}{360} \times\) ____
\(= \dfrac{45}{360} \times \dfrac{22}{7} \times 14 \times 14\)
\(=\) ____ cm²
Length of arc \(= \dfrac{\theta}{360} \times\) ____
\(= \dfrac{45}{360} \times 2 \times \dfrac{22}{7} \times 14\)
\(=\) ____ cm
