Question

Find the radius of a circle in which an arc of central angle 60 degree has length of 2phai . Hence find the area of the sector formed by this arc

Answer 1

Answer:

Step-by-step explanation:

theta/360 * 2pi r =l

Where l is the length of the arc.

Substituting values, we get

60/360* 2pi r=2pi

1/6*r=1

Therefore r= 6cm
