Question

The area of the sector of a circle whose radius is 6 m when the angle at the centre is ${42}^{\circ }$ is

• A. $13.2m^2$
• B. $14.2m^2$
• C. $13.4m^2$
• D. $14.4m^2$

Answer 1

Answer: (A)

$13.2m^2$

Area of sector $=\frac{42}{360}\times \pi r^2$
$=\frac{42}{360}\times \frac{22}{7}\times 6\times 6=13.2m^2$
