Given:

a.) The circumference of a circular pool is 7.8 meters.

Recall: The formula for getting the circumference of a circle.


\text{ Circumference = }\pi d

Where,

d = diameter of the circle

We get,


\text{ Circumference = }\pi d
\text{ 7.8 m = }\pi d
\text{ }\frac{\text{7.8}}{\pi}\text{ m = }d
\text{ }\frac{\text{7.8}}{3.14}\text{ m = }d
\text{ }2.4840764331\text{ m = }d\text{ }
\text{ }2.5\text{ m }\approx\text{ }d\text{ }

Therefore, the diameter of the circular pool is 2.5 m
