Question

The diameters of two touching circle are 15cm and 25cm respectively find the distance between their centres. ( consider both cases)

Answer 1

As both of the circles are touching each other the distance between their centres can be taken out by adding both the radius of the circle


Hence,

radius are 15/2 and 25/2 respectively

Therefore addition of these two is 20cm

Hope this and helps u!!

Answer 2

as the two circle are touching at a point
then the distance between the two centres
is equal to the sum of radii of the two circles.
distance =15/2+25/2=40/2=20cm

please mark it as brainliest answer please !!!!
