the angles which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal.
Radius = 3 units
Using pi as 3.132
Area of circle =

= 3.142 x 3 x 3 = 28.278 square units ≈ 28.28 square units
OR if you use the calculator and press pi x 3 x 3 = 28.27square units
There is ~ 52.15 weeks in a year.
