# Chapter 8 - Section 8.4 - Circumference and Area of a Circle - Exercises - Page 383: 6a

radius = 14 in diameter = 28 in

#### Work Step by Step

The circumference of the circle = 88 in The circumference of the circle is given by the formula c= $\pi$ d = 2$\pi$ r therefore 2$\pi$ r = 88 2*$\frac{22}{7}$*r = 88 r = $\frac{88* 7}{22* 2}$ = 14 in Therefore diameter of the circle = 2r = 2* 14 = 28 in
