The minimum number of common tagnents drawn to two circles when both the circles touch each other externally is

The number of common tangents that can be drawn to two given circles is at the most :

The two circles touch each other if

If two circles S=0 and s'=0 are touch each other externally then

How many common tangents can be drawn to two circles, touching each other externally?

What can be the maximum number of common tangent which can be drawn to two non-intersecting circles?

How many common tangents can be drawn when two circles touch each other internally.

The number of circles that can be drawn touching both the given circles is

If radii of two circles are 4 cm and 2.8 cm. Draw figure of these circles touching each other.
Externally.

PQ is a direct common tangent of two circles of radii $r_1\text{and}{r}_2$ touching each other externally at A. Then the value of $P{Q}^2$ is :

If radii of two circles are 4cm and 2.8cm . Draw figure of these circles touching each other
(i) externally
(ii) internally
