Question

For what value of k with line with equation x=6 to the tangent with circle of the equation x^2+y^2=k

Answer 1

The formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. If a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
