In this lesson, we will learn how to find the equation of a circle using its center and radius.

Q1:

Determine the equation of a circle with radius = 1 7 c m , given that it touches the π¦ -axis at the point ( 0 , β 7 ) , and its center lies in the third quadrant.

Q2:

Find the general form of the equation of circle π , given that it touches the two coordinate axes at π΄ and π΅ and that π π = 6 β 2 .

Q3:

What is the equation of the circle of radius 24 that lies in the third quadrant and is tangent to the two axes?
