10-1 Circles and Circumference
(where π≈3.14, d is diameter and r is radius)
Example: Find circumference if r = 13 inches
10-8 Equations of Circles
x and y are variables and must ALWAYS be in your answer!
(remember that the formula is x-h and y-k so when naming the center you do the opposite of the equation)
Find the radius by taking the square root of the number after the =
Plot the center and count out for the radius
