Question

The angle at center of circle subtended by arc is ${60}^{\circ }$ Find the length of arc if radius is $7cm$

• A. 14.6
• B. 15.6
• C. 16.6
• D. 17.6

Answer 1

The correct option is A 14.6

Angle subtended by arc is ${60}^{\circ }$

The radius of circle is $7cm$

The length of arc is given as $\frac{x}{360}\times 2\times \frac{22}{7}\times 7\frac{60}{360}\times 44\frac{1}{3}\times 44=14.6cm$
