Calculate the area of a circular round about of radius 2.8m.
The formula to calculate the area of a circle is A = πr^2, where r is the radius of the circle.
Given that the radius (r) of the roundabout is 2.8m, we can calculate the area as follows:
A = π(2.8)^2
A = π(7.84)
A ≈ 24.617 m^2
Therefore, the area of the circular roundabout with a radius of 2.8m is approximately 24.617 square meters.
