Ответ:
25 meters
Step-by-step explanation:
in this case they give us the information about the lake and that length corresponds to the perimeter.
the perimeter of a circle has the following formula:
p = 2 * pi * r
then r equals:
r = p / pi * 2
replacing we have:
r = 157 / (2 * 3.14)
r = 25
which means that the radius of the lake is 25 meters
