The circumference of a circle can be found by the formula

$S=2\cdot\pi\cdot r$

this can also be written in function of the diameter

$S=\pi\cdot D$

From this formula we can find the diameter

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

Using the information given, the diameter of the circle is

$D=(21.98)/(\pi)=6.996\approx7ft$
