Question

Find the area of sector, whose radius is 5 cm, subtending an angle of ${60}^{\circ }$.

• A. 13.09 ${cm}^2$
• B. 14.5 ${cm}^2$
• C. 16.5 ${cm}^2$
• D. 17 ${cm}^2$

Answer 1

The correct option is A 13.09 ${cm}^2$


$\because$ Area of sector = $\pi$$\times$$r^2$$\times$$\frac{x}{360}$
Given: $r$ = 5 $cm$ and $x$ = ${60}^{\circ }$
$\therefore$ Area of sector = $\pi$$\times$$5^2$$\times$$\frac{60}{360}$

= 13.09 ${cm}^2$
