Question 997372: Find the center and radius of the circle whose diameter has the given endpoints. Then use your answers to find the standard form of the equation of the circle.
The endpoints of the diameter are (4, 7) and (6, 15).
The center is ???.
The radius is ???.
The equation in standard form is ??? = ???.
Answer by josgarithmetic(39617)   (Show Source):
You can put this solution on YOUR website! Midpoint formula gives the center point of the circle, which will be (h,k).
Distance Formula for the endpoints will give the radius, r.
You need to know and be able to use both formulas.
Standard Form Equation model is (x-h)^2+(y-k)^2=r^2.
