When you find a diameter of a circle, you probably used this formula:
C = [tex] \pi [/tex]d
If we algebraically manipulate the formula, we get it to find the diameter with a circumference.
Divide both sides by [tex] \pi [/tex].
C / [tex] \pi [/tex] = [tex] \pi [/tex]d / [tex] \pi [/tex].
[tex] \frac{C}{ \pi } [/tex] = d
d = [tex] \frac{C}{ \pi } [/tex]
We know the circumference is 654 and we will use 3.14 for [tex] \pi [/tex].
Plug in the values.
d = [tex] \frac{654}{3.14} [/tex]
d ≈ 208.3
So, the diameter of the circle is about 208.3 units.
