Perform each of the following steps. Answered by amanfc7. You'll also need to be able to algebraically expand that equation. That is how to calculate the area of a circle in no time 😉.
If the center of the circle were moved from the origin to the point (h, k) and point P at (x, y) remains on the edge of the circle, which could represent the equation of the new circle? The common point is the center of the circle which is point S. Learn more about the circle; Yes, the area and circumference of a circle have the same value 4π if the radius of the circle has length 2.
