14 lut 2022 · Graph a Circle. Any equation of the form \((x-h)^{2}+(y-k)^{2}=r^{2}\) is the standard form of the equation of a circle with center, \((h,k)\), and radius, \(r\). We can then graph the circle on a rectangular coordinate system. Note that the standard form calls for subtraction from \(x\) and \(y\).
1. Two circles, called C1 and C2, are graphed below. The center of C1 is at the origin, and the center of C2 is the point in the first quadrant where the line y = x intersects C1. Suppose C1 has radius 2. C2 touches the x and y axes each in one point.
Write and graph the equation of a circle. Key Words. • standard equation of a circle. In the circle below, let point (x, y) represent any point on the circle whose center is at the origin. Let rrepresent the radius of the circle. In the right triangle, r5 length of hypotenuse, x5 length of a leg, y5 length of a leg.
