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 … WebJun 15, 2024 · Use ( h, k) as the center and a point on the circle. Formula: ( x − h) 2 + ( y − k) 2 = r 2 where ( h, k) is the center and r is the radius. Recall that a circle is the set of all points in a plane that are the same distance from the center. This definition can be used to find an equation of a circle in the coordinate plane. Figure 6.21. 1

WebAnother formula to find the circumference is if you have the diameter you divide the diameter by 2 and you get the radius. Once you have the radius you times the radius by 2 and … WebTo complete the square for the x terms, add 4 to both sides. The center of the circle is at (-2, 3). What is the radius of a circle given by the equation x2 + y2 - 2x + 8y - 47= 0? radius =. 8 units. A circle centered at (-1, 2) has a diameter of 10 units. Amit wants to determine whether (2, -2) is also on the circle. His work is shown below. theragun guide
