WebFind the equation of a circle with radius 3 units and centre (0, 0) The radius, \ (r = 3\) and \ (r^2 = 9\), so the equation of the circle is \ (x^2 + y^2 = 9\) Example What is the radius of... WebFeb 27, 2024 · Now to find the centre follow the below steps: Step 1: Compose the provided equation in the condition of the general equation of a circle – ( x − a) 2 + ( y − b) 2 = r 2, by adding or subtracting digits or numbers on both sides. We can write the given equation as x 2 – 6 x + y 2 – 4 y = 108.

WebA large collection of circles is called a family of circles. Circles having the same properties are combined together in various ways to form the family of circles. In this article, we will learn the formulas for the family of circles, along with solved examples. The general equation of a circle is given by x 2 + y 2 + 2gx + 2fy + c = 0 A circle is a closed curve that is drawn from the fixed point called the center, in which all the points on the curve are having the same distance from the center point of the center. The equation of a circle with (h, k) center and r radius is given by: (x-h)2+ (y-k)2= r2 This is the standard form of the equation. Thus, if we … See more Consider an arbitrary point P(x, y) on the circle. Let ‘a’ be the radius of the circle which is equal to OP. We know that the distance between the point (x, y) and origin (0,0)can be found using the distance formulawhich is … See more Let C(h, k) be the centre of the circle and P(x, y)be any point on the circle. Therefore, the radius of a circle is CP. By using distance … See more To find the polar form of equation of a circle, replace the value of x = r cos θ and y = r sin θ, in x2 + y2 = a2. Hence, we get; (r cos θ)2 + (r sin θ)2 = a2 r2 cos2 θ + r2 sin2 θ = a2 r2 (cos2 θ + sin2 θ) = a2 r2 (1) = a2[Using … See more The general equation of any type of circle is represented by: x2+y2+2gx+2fy+c = 0, for all values of g, f and c. Adding g2+f2on both sides of the equation gives, x2+2gx+g2+y2+2fy+f2= g2+f2−c………………(1) Since, (x+g)2 = x2+ 2gx + g2 and (y+f)2 =y2 + 2fy + f2substituting … See more simon\u0027s town school
