Mathematics: The point (5,4) lies on a circle. what is the length of the radius of this circle if the center is located at (3,2)

The x-intercept of a function is when the y-value is 0.Replace y with 0 in the equation. You get the following.Add both sides by 25Take the square root.This means that the x-intercepts are 5 and -5.A is your answer....

Use the x and y values from your point and the h and k from the center to write the equation you need to solve for r. The general form of the equation for a circle is $(x-h) ^{2} +(y-k) ^{2} = r^{2}$ . We will fill in accordingly: $(5-3) ^{2}+(4-2) ^{2} = r^{2}$ . Solve for r to get that $r= \sqrt{8}$
