Answer 1

A

Explanation:

One complete turn is 1 perimeter (aka circumference).

We have to find the length it turned, hence, its circumference.

The formula for circumference (C) of a circle is:

`C=2\pi r`

Where r is the radius

The radius is HALF of diameter. Given diameter is 250, the radius is:

r = 250/2 = 125 feet

Now, substituting in formula we have:

`C=2\pi r\\C=2\pi (125)\\C=250\pi\\C=785.4`

So, it turned 785.4 feet with 1 rotation.

The correct answer is A
