In this only u have to put the formula of Theta=L/R Let for 1st circle. Length be L Radius be R. Theta=60°=π/3 ....... Converted in radians. Therefore,..... Theta=L/R R=L/Theta.........(I) Therefore ... R=L/π/3....=3L/π. For 2nd circle . Length is same ...As A/c to question . Therefore Length=L Radius =R'. (Let) Theta=75°=7π/9.........(ii) Therefore, R'=L/7π/9. R'=9L/7π. ....... Now ratio...Of their radii... R/R'=3L/π÷9L/7π. R/R'=7/3. Ratio=7:3
