Question

two circles of the radii 10cm and 6cm touches each other from externally .what is the distance between the centre of that two circles​

Answer 1

AnswerCorrect option is

A

4

Let the radii of two circles be R  

1

​

 and R  

2

​

.

∴ R  

1

​

=10 and R  

2

​

=6

If two circles are touching internally then the common point lies on the line joining their centres.

Therefore, distance between their centres is R  

1

​

−R  

2

​

 

=10−6

=4

Step-by-step explanation:

Answer 2

Answer:

fact:- If the circles touches externally and ask for distance between their 's center then add the radius

if circles touches internally and ask for distance between their 's center then you need to be subtract their's radius.
