3. Ms. Calcutta, the owner of a business park is adding a recycling station for every three office buildings. To make it easier for the tenants, she is going to to use the circumcenter of the three office buildings to place the recycling stations. By doing this, it will be easier to get to the station, because it is equidistant from the three office buildings.

Part A; Justify the rationale behind Ms. Calcutta’s decision to use the circumcenter.

Part B: There is a garbage dumpster exactly at the midpoint of each pair of office buildings. Suppose that there are sidewalks connecting each office building to each other and to each recycling station. What is the relationship between the building-to-building sidewalk and the station-to-dumpster sidewalk?
