Question

[3]
Two circles of radii 6.5 cm and 4.8 cm touch each other externally.
Find the distance between the centres.​

Answer 1

Step-by-step explanation:

given that both the circles touch each other externally

that means distance between their centres is the sum of both the radius

i.e., distance between their centres = 6.5 +4.8

distance between their centres is = 11.3 cm

Answer 2

Answer: - 1.7 cm

Step-by-step explanation:

Given :-

Two circles of radii 6.5 cm and 4.8 cm touch each other externally.

To Find :-

The distance between the centres.

Solution :-

We know that, concentric circle means two or more than two circles with a common center point .

.

Where,

Bigger radius, R = 6.5 cm

Smaller radius, r = 4.8 cm

= R - r

➝ 6.5 - 4.8

➝ 1.7 cm
