Answer: 43.96 miles

FORMULA FOR CIRCUMFERENCE OF A CIRCLE: C=d•pi

In this case that would be 14 • 3.14, which would give you a answer of 43.96

IM SO SORRY IF THIS DIDN’T MAKE SINCE!

Answer:


C = 43.96 \text{ miles}

Explanation:

The circumference (perimeter) of a circle is defined as:


C = \pi \cdot d,

where
d is the circle's diameter.

We can plug in 14 for the diameter and 3.14 for π, then solve for C.


C = 3.14 \cdot 14


C = 43.96 \text{ miles}

Note that we can also write the circumference formula as:


C = 2\pi r

because
d = 2\cdot r.
