This means that its center must be located at 4 3 and its radius is 29.
Find the equation of a circle math. Circle a first has the equation of x 4 2 y 3 2 29. The formula is x h 2 y k 2 r 2. And you also know that the diameter is 18 and since a radius equals one half of the diameter r 18 2 9 so the radius is 9. Is a way to express the definition of a circle on the coordinate plane.
The general equation of a circle is x h 2 y k 2 r 2 where h k represents the location of the circle s center and r represents the length of its radius. You already know that the center is at the origin which is 0 0 so h 0 and k 0. The standard form of an equation of a circle is x h 2 y k 2 r 2. Find the center and radius of the circle having the equation.
The radius is r the center of the circle is h k and x y is any point on the circle. H and k are the x and y coordinates of the center of the circle x 9 2 y 6 2 100 is a circle centered at 9 6 with a radius of 10. To write the equation of circle j you need to know the center coordinates and the length of the radius. You can input integers 10 decimals 10 2 fractions 10 3 and square roots use letter r as a square root symbol.
The radius is r the center of the circle is h k and x y is any point on the circle.
