When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- In a circle, a 90° sector has area #16pi# #ft^2#. What is the radius of the circle?
- Two circles have the following equations: #(x +6 )^2+(y -5 )^2= 64 # and #(x -2 )^2+(y +4 )^2= 81 #. Does one circle contain the other? If not, what is the greatest possible distance between a point on one circle and another point on the other?
- A circle has a chord that goes from #( pi)/2 # to #(5 pi) / 4 # radians on the circle. If the area of the circle is #196 pi #, what is the length of the chord?
