The length of an arc of a circle is twice the length of the radius. Find the angle subtended by the arc at the centre of the circle in degrees.

length of an arc = x/360*2*pi*r

Given, length of arc = 2r

therefore, 2r=(x/360)*2*22/7*r

hence, x = 114.1 degrees

few points..
1) Q is not GMAT type - pattern or otherwise..
2) pl post Q properly.
3) it is not TOO hard
4) no one will ask you degree and minutes

your query..
radius is r
circumference or 2*pi*r makes an angle 360 at centre ..
2r will make an angle 360/pi= 360*7/22 nearly equal to 114 degree....
