Question

Write equation of circle in standard form. Quadrant lies in 2 tangent to x=–12 and x=–4

Answer 1

Solution

Explanation:

The diameter of the circle is defined by the distance between (-12, 0) and (-4, 0).

The distance from the mid point of the line joining points (-12, 0) and (-4, 0) to point is the radius of the circle = 4
