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. campground liability waiver

How to Find the Perimeter or Circumference of a Circle? Formula

The perimeter of a circle, often called the circumference, is proportional to its diameter and its radius. That is to say, there exists a constant number pi, π (the Greek p for perimeter), such that if P is the circle's perimeter and D its diameter then, In terms of the radius r of the circle, this formula becomes, To calculate a circle's perimeter, knowledge of its radius or diameter and the number π suffices. … WebbThe formula to calculate the perimeter of a circle or circumference formula can be given as: The perimeter of a circle = 2 π r = π D units where, r = radius of the circle D = diameter of the circle Examples of Perimeter of Circle Formula Let us solve some interesting problems using the perimeter of the circle formula.
