Given : The center has a circular pond with a diameter of 20 meters.
To find : What is the approximate area of the pond.
Solution: We have given diameter = 20 meters.
Radius = .
Radius = .
Radius = 10 meter .
Area of circular pond = pi ( radius) ².
Area of pond = 3.14 (10) ².
Area of pond = 3.14 * 100.
Area of pond = 314 meter².
Therefore, Area of pond = 314 meter².
