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

[tex]C = \pi * d[/tex]

Where:

d: It is the diameter of the circle

They tell us that the radius of the circle is 125 meters, then the diameter is 250 meters.

Substituting:

[tex]C=3.14*250\\C=785\m[/tex]

Thus, the circumference of the circle is 785 meters

ANswer:

785 meters

Answer:

The correct answer is option B.  785 m

Step-by-step explanation:

Points to remember

Circumference of a circle = 2πr

Where r is the radius of circle

To find the circumference of circle

Here r = 125 m and π = 3.14

Circumference = 2πr

 = 2 * 3.14 * 125 = 785 m

The answer is  785 m

Therefore the correct answer is option B.  785 m
