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

The circumference of the circle = 44$\pi$ in The circumference of the circle is given by the formula c= $\pi$ d = 2$\pi$ r therefore 2$\pi$ r = 44$\pi$ 2r = 44 r = $\frac{44}{2}$ = 22 in Therefore diameter of the circle = 2r = 2* 22 = 44 in
