Notice that the distance formula results in a real number and that the midpoint formula results in an ordered pair.
[ Interactive: Distance and Midpoint ]
Given two points find the distance and midpoint between them.
- Distance Formula ( Proof and Example )
- Midpoint Formula ( Proof and Example )
Example: If the diameter of a circle is defined by the two points (-3, 4) and (7, 4), find the center and radius of the circle. (Hint: diameter = 2r)
Example: Find the area of a circle given center (-3, 3) and point (3, 3) on the circle.
