## Elementary Geometry for College Students (6th Edition)

The circumference of the circle = 157 m The circumference of the circle is given by the formula c= $\pi$ d = 2$\pi$ r therefore 2$\pi$ r = 157 2*3.14*r = 157 r = $\frac{157}{3.14* 2}$ = 25 m Therefore diameter of the circle = 2r = 2* 25 = 50 m
