Find the center and radius calculator
How do you find the general equation of a circle?
The general equation of a circle is x2+y2+ 2gx+ 2f y+c= 0, where the centre is given by the radius byr=+f2c. The equation can(−g,−f)andpg2−be recognised because it is given by a quadratic expression inbothxandywith noxyterm,and where the coefficients of x2andy2are equal.
How do you find the degree of a curve?
SELECTING THE DEGREE OF CURVE Curves are usually fitted to tangents by choosing a D (degree of curve) that will place the centerline of the curve on or slightly on or above the gradeline. Sometimes D is chosen to satisfy a limited tangent distance or a desired curve length. Each of these situations is discussed below:
How do you find the length of a curcurve?
Curve data can be calculated using the adjusted radius or by proportioning the center line data. The subscripts “o” for outside and “i” for inside are commonly used to identify elements on offset curves. For example, the length of an inside curve would be Li= (π/180) R i∆ ; Ribeing a shorter radius than the center line radius R.
How do you find the center of bend of a conduit?
Multiply the (C-C) measurement of the conduits by the tangent of 1/2 the bend angle. Add this figure to the center of bend measurement of 1st conduit. This will be center of bend measure-ment of the 2nd conduit. Advance the center of bend measurement of each succeeding conduit by this figure.

For example, the length of an inside curve would be Li = (π/180) R i ∆ ; Ri being a shorter radius than the center line radius R. Or, by proportion, Li = (Ri /R) L.

Find the centre and radius of the circle x2 +y2 − 6x+4y − 12 = 0. Solution First, we can check that the expression on the left-hand side is quadratic, that there is no term involving xy, and that the coefficients of x2 and y2 are equal. So this is the equation of a circle.
