) Calculate the compaction index for this shape.

In order to determine the area of the shape, use the grid method discussed in class. Remember that

Area of shape = (a + (b/2)) * area of grid cell

where:

a = number of whole grid cells within the shape, and b = number of cells through which the boundary of the shape passes.

Assume that:

• the circle surrounding the shape is centered at X = 9.5, Y = 19.5, with a radius of 11.36
• the area of the circle is r², where is the mathematical constant 3.142 and r is the radius of the circle.
