Question 1083072: Write the equation in standard form for the circle with center (0,9) passing through (4,33/2) Found 2 solutions by Boreal, solver91311:Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! The radius is needed and the distance formula will find it.
sqrt{(4^2+7.5^2)=sqrt(72.25)=8.5. Actually, don't need the square root since the equation of a circle deals with the square of the radius.
x^2+(y-9)^2=72.25
The standard form of an equation of a circle centered at and with radius is:
You are given the center and a point on the circle. Use the given coordinates of the center directly and calculate the radius by using the distance formula applied to the two given points.
