Circular segment - Wikipedia
WebThe standard equation for a circle centred at (h,k) with radius r is (x-h)^2 + (y-k)^2 = r^2 So your equation starts as ( x + 1 )^2 + ( y + 7 )^2 = r^2 Next, substitute the values of the given point (2 for x and 11 for y), getting 3^2 … WebFeb 22, 2024 · The formula is given as: Circumference of a circle = 2 (pi) (r) = (pi)d. where r is the radius of the circle, d is the diameter, and the value of pi is 3.14. The radius of a circle is a line segment that joins the center of the circle to any point on the circle’s circumference. It is half of the length of the diameter. WebA = π r 2. A=\pi r^2 A = πr2.
