GOAL: To redesign the bus route zones in a city based on circles and their equations.
ROLE: You are the City Zoning Commissioner.
The bus routes need to be redesigned to be more cost effective. You
are trying to avoid cutting jobs by making the zones more efficient.
Many Port Authority workers are depending on you to save their jobs.
You have been chosen to determine the best way to redesign the bus
routes. Zone 1 will cover people living within 3 miles of the city
center. Zone 2 will cover people living between 3 and 7 miles from the
center of the city. Zone 3 will cover people living between 7 and 10
miles from the center of the city. Consider the center of the city the
origin on the coordinate plane and each unit on the coordinate plane
equal to one mile.
Determine the equation of the circles for Zone 1, Zone 2, and Zone 3.
Show all work and explain how you arrived at your answers. 2.
Determine the area of each zone using the area formula for circles (A =
3.14xRadius^2). Show all work and explain how you arrived at your
answers. Round to the nearest whole number. 3. Your house is located at (-1,3). What Zone do you live in? Show your work and explain how you arrived at your answer.
