A rail road curve is to be laid out on a circle. If the track is to change its direction by 28 degrees in a dist. of 44 m then the radius of the curve is? ans:d = 2πrθ/360 => 44 = 56πr/360 =>r = (360*44)/56π =>r = (360*44*7)/56*22 =>r = 90min this solution derive for:d = 2πrθ/360

we aleady know that d=rθ hereθ is in radian and 360=2π radian 1 =2π/360 just convert this radian in degree now
