## heatjack13 Group Title The circumference of a circle is 50.24 centimeters. Find the radius of the circle. (Use 3.14 for π.) 2 years ago 2 years ago

1. Avva

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

4. Avva

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