a.
To calculate: The sectors' total regions, double regions, and treble regions.
The sector's total area is approximately
Given information: Considering that there are
Calculation:
Value of r
Value of
Value of
Value of
The territory of a single sector is divided into
The area of double region
The area of the triple region
Conclusion:
The sector's total area is approximately
b.
To calculate: The likelihood that a geographical mass will be in a double or triple region.
The chance of a double area
Given information: A dart is thrown at random and lands somewhere inside the sector, with a chance that it will most likely land in the double or triple region.
Calculation:
The ratio between the area of the region
The ratio is now: Since the area of the double region is approximately
The ratio between the area of the sector as a whole and the area of the triple region will represent the likelihood that something will land there.
Given that the total sector covers an area of around
Conclusion:
The chance of a double area
