The formula for the area of a circle is A = πr^2.
Given that the area of the pool is 28 square meters, we can set up the equation as follows:
28 = πr^2
To solve for r, we can divide both sides of the equation by π:
r^2 = 28/π
r^2 ≈ 8.92
Taking the square root of both sides gives us:
r ≈ √(8.92) ≈ 2.99
Therefore, the radius of the pool, rounded to the nearest whole meter, is 3 meters.
