    circumference of circle \[= \Pi r ^{2}\] you are given the circumference , pi is given so only one unknown parameter you can calculate \[r = \sqrt{\frac{ c }{ \Pi }} \] where c is the circumference I took only the +ve vale for the square root as it is radius "length" so it can't be a negative value

    it will be \[\sqrt{\frac{ 50.24 }{ 3 }} = 4 cm\]
