Answer 2

The area of sector of a circle is equal to 25.67 $cm^{2}$.

Step-by-step explanation:

Given,

The radius of sector of a circle (r) = 7 cm and

Sector angle ($\theta$) = 60°

To find,  the area of sector of a circle = ?

We know that,

The area of sector of a circle = $\dfrac{\theta}{360} \pi r^{2}$

= $\dfrac{60}{360}\times \dfrac{22}{7} \times 7^{2}cm^{2}$

= $\dfrac{1}{6}\times \dfrac{22}{7} \times 7\times 7cm^{2}$

= $\dfrac{77}{3} cm^{2}$

= 25.67 $cm^{2}$

∴ The area of sector of a circle = 25.67 $cm^{2}$

Thus, the area of sector of a circle is equal to 25.67 $cm^{2}$.
