Question 265649
<font face="Garamond" size="+2">


The circumference of a circle is given by:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ C\ =\ \pi d\]


but we know that


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ d\ =\ 2r]


Hence


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ C\ =\ 2\pi r]


Solving for *[tex \Large r]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ r\ =\ \frac{C}{2\pi}]


Plug in your value for *[tex \Large C] and do the arithmetic.  Round your answer to three decimal places to match the precision of your given measurement.
