Find the exact value of the arc length intercepted by a cent

Find the exact value of the arc length intercepted by a central angle of 205 degree in a circle a radius of 3 centimeters.

Solution

given cetral angle =205^o , radius r =3 cm

arc length L =r(/180^o)

arc length L =3*205^o(/180^o)

arc length L =10.734 cm
