Question

if the circles with diameter 8 cm and 3cm respectively touch externally then find the distance between the centres​

Answer 1

Step-by-step explanation:

It is given that two circles with radii 8cm and 3cm touch externally.

We need to find the distance between the centres of these two circles.

We know that ,

If any two circles touch externally then the distance between their centres is the sum of their radii.

According to the given question,

Diameter of first circle = 8cm

So it's radii = 4cm

Diameter of second circle = 3cm

So it's radii = 1.5cm

Distance between their centres :

4 + 1.5 = 5.5cm
