Answer to: Find the center and radius of the circle. Graph the circle. Find the intercepts, if any, of the circle. x^2 + y^2 + 4x - 4y - 1 = 0 By...
To find the center and radius of the circle given by the equation 2x2+2y2=3x−5y+7, we will follow these steps: Step 1: Rearrange the equationFirst, we need to rearrange the equation to bring all terms to one side:2x2+2y2−3x+5y−7=0 Step 2: Divide by 2Next, we divide...
Find the radius( r) for the circle. 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 ...
Centre is (-5, 6) and radius is 2sqrt(13).Find the centre and radius of the circle x^2+y^2+10 x-12 y+9=0
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...
Because all circles have the same shape, their different measurements are related by a set of simple equations. If you know the radius, diameter, area or circumference of a circle, it is fairly easy to find any of the other measurements.
The given equation of the circle- $$(x-3)^{2} + (y-1)^{2} = 25 $$ Here to find out the center and radius of the circle we have to convert it into... Learn more about this topic: Radius of a Circle Formula & Example | How to Find the Radius of a ...
