(iii)If two circles cut a third circle orthogonally; then the radical axis of two circle will pass through the center of the third circle .

Radical Axis Of Two Circles

If two circles each of unit radius intersect orthogonally,the common area of the circles is

The radii of two circles are 15 cm and 8 cm.If the area of a third circle is equal to the sum of the areas of the two circles, then what will be the radius of the third circle?

(iv) The position of the radical axis of the two circles geometrically is as:

One circle has a radius of 5 and its centre at (0,5). A second circle has a radius of 12 and its centre at (12,0). What is the length of a radius of a third circle which passes through the centre of the second circle and both the points of intersection of the first two circles.

The radii of two circles are 20 cm and 15 cm respectively. If a third circle has an area which is equal to the sum of the areas of the two given circles, what will be the radius of the third circle?

(a,c) and (b,c) are the centres of two circles whose radical axis is the y-axis.If the radius of the first circle is r then the diameter of the other circle is
