Center-radius formula r (x−h)2+(y−k)2=r2 Answer and Explanation:1 The equation of the circle below is in the circle-radius form: (x+3)2+(y−5)2=16 If we compare it to the cirle-radius form of a... Learn more about this to...
The center of this circle is (−9, 6), with a radius of 10. The equation (x+9)² + (y−6)² = 10² is in the standard circle equation form (x−A)² + (y−B)² = C, making A = −9 and B = 6. What is the center of a circle represented by the equat...
The radius is any line segment from the center of the circle to any point on its circumference. In this case, ( r) is the distance between ( (2,-2)) and ( (-5,-1)). ( r=5√2) ( ((x-h))^2+((y-k))^2=r^2) is the equation form for a circle with ( r)radius an...
For example, the ratio of the centroid's triangle functions and is , where is the circumradius of . Hence, they are equivalent triangle center functions. Note also that it is common to give triangle center functions in an abbreviated form that does not explicitly satisfy bisymmetry, but ...
Multiply each term on both sides of the equation by ( 121). ( x^2+y^2=121) This is the form of a circle. Use this form to determine the center and radius of the circle. ( ((x-h))^2+((y-k))^2=r^2) Match the values in this circle to those of the standard...
To find out the center and radius of a circle, first of all, convert the given equation into the center-radius form by completing the square in {eq}x {/eq} and {eq}y {/eq} variable and then compare it with the standard center-radius form of the circle. ...
Find the center-radius form of the equation of circle with center (2,4) and tangent to the y-axis. (Hint: A line tangent to a circle touches it at exactly one point.) Find the center-radius form of the equation of the circle with center (...
