Question

Radius of a circle is $7cm$ and angle subtended at the center is ${60}^{\circ }$. Find the length of the arc.

Answer 1

Angle subtended by arc is ${60}^{\circ }$
The radius of the circle is $7cm$
The length of the arc is given as
$=\frac{x}{360}\times 2\times \frac{22}{7}\times 7$
$=\frac{60}{360}\times 44$
$=\frac{1}{3}\times 44=14.6cm$
