The floor of a circular pool has an area of 28 square meters. What is the radius of the pool, rounded to the nearest whole meter
The formula for the area of a circle is A = πr^2, where A is the area and r is the radius.
Given that the area of the circular pool is 28 square meters, we can set up the equation:
28 = πr^2
Solving for r, we divide both sides of the equation by π:
r^2 = 28/π
r^2 ≈ 8.91
Taking the square root of both sides, we find:
r ≈ √8.91 ≈ 2.99
Rounded to the nearest whole meter, the radius of the pool is 3 meters.
