V = 3.14 * 2500 = 7850
depending on what decimal you use for pi, your answer will differ
Note that while the figure is made up of rectangle and parallelogram, then the area of this figure
1. The area of rectangle is
The vertices of rectangle are points A(-2,-2), B(0,-6), C(8,-2) and F(6,2). Then
Therefore,
2. The area of parallelogram can be calculated using formula
The base of parallelogram is segment CD with length
and the height has length 2 un. Then
3. Now
