The area in which the cran can operate is 2,461.76 m²
circular area can the crane operate?
360° would define a circle, and in this case the circle will have a radius of 28 meters, then the area in which the crane can operate is a circle with a radius of 28m.
For a circle of radius R, the area is:
A = pi*R²
Where pi = 3.14
Here we will get the area:
A = 3.14*(28m)²
A = 2,461.76 m²
