    Are you trying to solve for the radius of a circle when the circumference is given?

    The formula for circumference of a circle is \[C=2\pi r=\pi D\] where C is circumference r is radius D is diameter. so give that circumference is 42. if you need diameter then you get \[D=\frac{C}{\pi}=\frac{42}{\pi}=\frac{42}{3.1415}\]
