Homeownership has other expenses, including property taxes, homeowner's insurance, and utilities. The annual property tax can be estimated as 1% of the amount borrowed and the
annual homeowner's insurance can be estimated as 2% of the amount borrowed.
7. For a mortgage of $165,000, find the following.
a. What is the MONTHLY amount of property tax.
b. What is the MONTHLY amount of homeowner's insurance.

The arc length in degrees (same as central angle that cuts it off) is to 360 (degrees in a circle) AS the arc length in linear measure is to the circumference of the circle (2 pi r).
90/360 = AL/[2 pi (85)] where AL is the arc length in linear measure.
 1/4 = AL/[170 pi]
4 AL = 170 pi
 AL = 42.5 pi
 AL = 133.45 feet (approx)
