Question
If the radius of a circle is 7 and the center is at (-2, 5), find the equation of the circle. If the major axis of an ellipse is 10 and lies on the x-axis, and the minor axis is 8 and lies on the y-axis, find the equation of the ellipse. Name and graph the conic section: (x - 1)^2 + y^2 = 15 Name and graph the conic section x^2 + 2x - y = 3 Name and graph the conic section: 9x^2 - 16y^2 - 144 = 0 Name and graph the conic section: 9x^2 + 16y^2 - 144 = 0 Name and graph the conic section: x^2 + y^2 - 2y = 0 Find the distance between the points (3, 7) and (6, 3) Find the distance between the points (-4, 1) and (2, 5) Find the equation of the circle with center (2, 5) and passing through the point (-1, 4).Explanation / Answer
radius =7 , center =(-2,5)
Equation of circle with radius r and center (h k) is
(x-h)2+(y-k)2=r2
So we get
(x+2)2+(y-5)2=72=49
(x+2)2+(y-5)2=49
