Find the center radius form for each circle having the given endpoints of a diameter. 22. (-4,5) and (6,-9)

26. ( 0,9) and (0,-9)

22.  

26.  

Step-by-step explanation:

The center of a circle is the midpoint of the diameter.

(where and are the endpoints of the diameter)

The radius of the circle is the distance between the center and an endpoint of the diameter.

(where is the center of the circle, and is an endpoint of the diameter)

The center-radius form of a circle:

(where (a, b) is the center and r is the radius)

Question 22

Question 26

⇒ equation of circle:

answer: 230 miles ( vote ! )

step-by-step explanation:

180.39 minus 17.99 equals 162.4

then divide 162.4 by .80 to get 230
