Given: Two circles with diameter 14cm and 10cm respectively touch externally
To find: The distance between their centres.
Explanation: The radius of the larger circle with diameter 14 cm = diameter/2
= 7 cm
The radius of the shorter circle with diameter 10 cm = diameter/2=10/2
= 5 cm
The distance between the centres of the circles when they touch externally= sum of radius
= 7+5= 12 cm
Therefore, the distance between the centre of circles is equal to 12 cm.
