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.
It isn't different, it is very much the same 1-1 = 0 .1-.1 = 0 5.25 - 3.75 = 1.50 1.0005 +1.005 = 2.0055 just make sure to line the decimal places on top of each other <span />
