The quotient between the circumference of a circle and its diameter is always the same and it is a constant denoted as π:

$\pi=(C)/(D)$

π is an irrational number and its first digits are:

$3.141592653\ldots$

Isolate C from the given relation and substitute D=1,400mi to find the circumference of Pluto:

$\begin{gathered} C=\pi D \\ =(3.141592653\ldots)*(1400mi) \\ =4398.229715\ldots mi \\ \approx4400mi \end{gathered}$

Therefore, the circumference of Pluto is approximately 4,398 miles.
