Question

Distance between two external touching circles with radii 2cm and 2.5cm is​

Answer 1

Step-by-step explanation:

Given :-

Radii of the two circles are 2 cm and 2.5 cm

To find :-

Distance between two external touching circles?

Solution :-

Given that

Radii of the two circles are 2 cm and 2.5 cm

r1 = 2 cm

r2 = 2.5 cm

If they are touching externally

We know that

If two circles touches externally then the distance between two centres of the circles is the sum of the two radii of the circles.

=> Distance = r1 + r2

=> Distance = 2 + 2.5

=> Distance = 4.5 cm

Answer:-

The distance between two centres of the two circles is 4.5 cm

Used formulae:-

"If two circles touches externally then the distance between two centres of the circles is the sum of the two radii of the circles".

Answer 2

Answer:

Step-by-step explanation:

D= r+ r

D= 2+ 2.5

D= 4.5 cm
