How to verify midpoint using distance formula

Step-by-step explanation:

Suppose you draw line AC and calculate the midpoint of AC.

To verify the correctness of your midpoint, you'd find the distance from A to the midpoint, M, as well as the distance from the midpoint, M, to C.  If these two distances are equal, then you've found that your midpoint calculation was correct.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
