Find the center of the circle. Write the standard form of the equation.

1, (5.5, 4)

2. r = 2.5

3.  

Step-by-step explanation:

1.  To find the center of the a circle with points (3,4) and (8,4), you can connect those and see that they create the diameter.  To find the center, just use a midpoint formula. [ (3+8)/2 , (4+4)/2 ] = (11/2 , 4) or (5.5,4)

2.  The radius is half the length of the diameter.  Since the diameter is based on the horizontal length, just subtract the x-values.  So 8-3 = 5.  Diameter = 5, so the Radius is half of that.  r = 5/2 = 2.5

3.  The standard for of a circle is where (h,k) is your center and r is your radius.  So just plug those in.
