Answer:

C = 8π

Explanation:

The circumference (C) of a circle is calculated using

C = πd ← d is the diameter

here d = 8, hence

C = 8π ft ← exact value

For this case we have by definition, that the circumference of a circle is given by:

$C = \pi * d$

Where:

d: It is the diameter of the circle

We have as data that the diameter of the circle measures:8ft, then, replacing:

$C = \pi * 8$

Finally, the circumference is
$8\pi$

ANswer:

$8\pi$
