Use the information provided to write the standard form equation of each circle. 1) Center: (-11, -8) Radius: 2.
•find the centre and radius of a circle, given its equation in standard form; •find the equation of the tangent to a circle through a given point on its circumference; •decide whether a given line is tangent to a given circle.
What is the equation of the circle? To determine the equation of a circle, we need the center and the radius. Center is the midpoint of the diameter's endpoints. The radius is 1/2 the length of the diameter... Using the distance formula to find the length: 36+64 Radius: 5 Center (h, k): (4, O) (to check, plug in both endpoints
Math Formulas: Circle. Equation of a circle. In an. x y. coordinate system, the circle with center. (a; b) and radius. r. is the set of all points.
Circle Formula Sheet Name Formula Explanation Radius r = d ÷ 2 The distance to the centre of the circle. The radius is half as long as the diameter. Diameter d = 2r The distance across the circle through the centre. The diameter is twice as long as the radius. Circumference C = π d or C = 2 π r The distance around a circle is called the
