A secular swimming pool has a diameter of 20 m the bottom of the pool needs to be repainted every year to maintain its appearance if the cost of the pain is three dollars per square meter what is the approximate cost to repaint the pool?
The formula to calculate the cost of painting the bottom of the pool is:
Cost = Area * Cost per square meter
First, calculate the area of the bottom of the pool:
Radius = diameter / 2 = 20m / 2 = 10m
Area = π * (radius)^2
Area = π * (10m)^2
Area ≈ 314.16 m^2
Now, calculate the cost of repainting:
Cost = 314.16 m^2 * $3/m^2
Cost ≈ $942.48
Therefore, the approximate cost to repaint the bottom of the pool is approximately $942.48.
