Write the equation of the circle with center at (0, 0) and a radius of 6.Ĭenter and radius of the circle whose equation is given by: (x - 2) 2 + (y + 5) 2 = 13įind the center and radius of the circle whose equation is given by: (5 - x) 2 + (y - 1) 2 = 4įind the center and radius of the circle whose equation is given by: (-4 - x) 2 + (-y + 11) 2 = 9įind the center and radius of the circle whose equation is given by: x 2 + y 2 + 6x - 10 y = 9įind the center and radius of the circle whose equation is given by: x 2 + y 2 + 4y = 0įind the center and radius of the circle whose equation is given by: -x 2 - y 2 + 8x = 0įind the equation of a circle that has a diameter with end points (-6, 1) and (2, -5).įind the point(s) of intersection of the circle with equation x 2 + y 2 = 4 and the circle with equations (x - 2) 2 + (y - 2) 2 = 4.įind the equations of the circle with center at (-3, 5) and passes through the point (5, -1).įind the equations of the circle that passes through the points (0, 6), (0, 0) and (8, 0). The set of all points in a plane that are equidistant from a fixed point, defined as the center, is called a circle. This is a circle centred at (1, 2) with a. Answers to these questions are also provided and are located at the lower part of the page.įind the distance between the points A(3, 4) and B(5, 8)įind x so that the distance between the points (x, 4) and (-5, 3) is equal to 5. We have converted x2 + y2 2x 4y 4 0 (in general form) to (x 1)2 + (y 2)2 9 (in standard form). A set of math questions on circles and distance bewteen two points are presented. Apollonius, in about 240 BC, showed effectively that the bipolar equation r k r r kr rkr represents a system of coaxial circles as k k k varies.
