Question

The radiud of a circle is 6m. And calculate the thr lenght of arc of cicle if the angle subtended by the arc at the center is 180degree.

Answer 1

Answer:

$\sf{Length \ of \ arc=\dfrac{\theta}{360}\times2\pi \ times \ r}$

$\sf{for \ \theta=180}$

$\sf{Length \ of \ arc=\pi\times \ r}$

$\sf{Length \ of \ arc=3.14\times6}$

$\sf{Length \ of \ arc=18.84 \ m}$
