The circle's "radius" refers to the distance from the center towards the circumference. Once the diameter of a circle is given, it is easy to get the radius. In order to get the length of the circle's radius, all you have to do is to divide the diameter<em> (55 inches) </em>into two.
55 inches ÷ 2 = 27.5 inches
Therefore, the circle's distance from the center towards the circumference is <em>27.5 inches.</em> This is the radius.
