Suppose a circle of radius r is inscribed in a hexagon. What is the *perimeter* of the hexagon? Thanks!
Let length of each side of the regular hexagon circumscribing the circle of radius
Then obviously
So perimeter of the hexagon will be

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.

- A triangle has corners at #(5 ,6 )#, #(4 ,3 )#, and #(2 ,5 )#. What is the area of the triangle's circumscribed circle?
- A circle's center is at #(3 ,1 )# and it passes through #(4 ,2 )#. What is the length of an arc covering #( pi ) /6 # radians on the circle?
- Points #(2 ,2 )# and #(8 ,1 )# are #(5 pi)/3 # radians apart on a circle. What is the shortest arc length between the points?
- A triangle has vertices A, B, and C. Vertex A has an angle of #pi/8 #, vertex B has an angle of #(pi)/12 #, and the triangle's area is #12 #. What is the area of the triangle's incircle?
- A triangle has vertices A, B, and C. Vertex A has an angle of #pi/2 #, vertex B has an angle of #( pi)/3 #, and the triangle's area is #56 #. What is the area of the triangle's incircle?
