The equation of a circle with center (0,2) and radius r is x^2+(y-2)^2=r^2 Since it passes through (0,0) (the origin) 0^2+(0-2)^2=r^2 r^2=4 The equation of the circle is x^2+(y-2)^2=4
How do you find the center and radius of x2 Y2 16?
You need to think of that equation in terms of the classic definition of a circle: (x - a)2 + (y - b)2 = r2 where a and b are the center of the circle, x and y are any point on it's circumference, and r is it's radius. In the case of the circle you're looking at: x2 + y2 = 16 You can re-express it like this: (x - 0)2 + (y - 0)2 = 42 So that circle has a center at the point (0, 0), and a radius of 4.
What is the equation for a circle with a center of -4 0 and a radius of 10?
The general formula: (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center and r is the radius. So the required equation of the circle is: (x - -4)^2 + (y - 0)^2 = 10^2 (x + 4)^2 + y ^2 = 100
What is the distance chords are from the center of a circle?
Any value from 0 to the magnitude of the radius.
What is the center and the radius of the circle x2 plus y2 -4x -6y -3 equals 0?
Equation of circle: x^2 +y^2 -4x -6y -3 = 0 Completing the squares: (x-2)^2 +(y-3)^2 = 16 square units Therefore center of circle is at (2, 3) and its radius is 4 units
What is the equation of the circle that touches the x axis when its center is at 2 5?
Center of circle: (2, 5) Point of contact with the x axis: (2, 0) Distance from (2, 5) to (2, 0) equals 5 which is the radius of the circle Equation of the circle: (x-2)^2 +(y-5)^2 = 25
What is the center and radius of the circle x2 plus y2 -10x plus 6y -15 equals 0?
