This is an answer for an example question using this solve your question

Given Data : length of arc =25 cm ? = angle subtended at the centre of circle = 55° Formula to be used : Length of arc = θ360∗2πrcm =5536∗2πrcm As given in the question length of arc =25 cm ,hence, 25 cm =55360∗2π∗rcm 25 = 11πr36 radius=25∗3611∗π = 90011π Therefore, the radius of the circle is 90011π
