The area of a sector (in $c m^{2}$ )of a circle with radius 6 cm if angle of the sector is $70^{\circ}$ will be __ . ( Take $π$ = $\frac{22}{7}$ )

Open in App

Solution

Given that radius r = 6 cm
$θ$ = $70^{\circ}$
Area of sector of an angle $θ$ with radius r = $\frac{70}{360}$ × $\frac{22}{7}$ × $6^{2}$
= 22 $c m^{2}$
