Question

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

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

Answer 1

The correct option is A $13.2m^2$

Area of sector $=$ $\frac{\theta }{{360}^0}\times \pi r^2=\frac{{42}^0}{{360}^0}\times \frac{22}{7}\times 6\times 6=13.2m^2$
