The circumference of a circle is 50.24 centimeters. Find the radius of the circle. (Use 3.14 for π.)
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
its one of these ansers
8 cm 16 cm 4 cm 2 cm
it will be \[\sqrt{\frac{ 50.24 }{ 3 }} = 4 cm\]
