The formula for the circumference of a circle is
$2\pi d$ . Substituting d = 14 into this gives us
$28\pi \text{ feet}$ .

Simplifying using
3.14 as
$\pi$ gives us
$3.14 \cdot 28 = 87.92 \text{ feet}$ .

Simplifying using
3.14159 as
$\pi$ gives us
$87.96452 \text{ feet}$ .

Simplifying using
(22)/(7) as
$\pi$ gives us
$88 \text{ feet}$ .

Hope this helps! :)
