WebJan 11, 2024 · radius (the distance from the center to the circle) chord (a line segment from the circle to another point on the circle without going through the center) secant (a line passing through two points of the circle) diameter (a chord passing through the center) circumference (the distance around the circle itself.
WebWe know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. So add 21 to both sides to get the constant term to the righthand side of the equation. x^2 + y^2 -4y = 21. Then complete the square for the y terms. x^2 + y^2 - 4y + 4 = 21 + 4.
