Math, asked by grv786, 1 year ago

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

no2: which could be the two cases

no2: pls tell so tht i can answer

no2: it would be touching

no2: the small circle is in the big circle

no2: or they r cutting each other

grv786: no have any diagram in question only this

no2: what???

if the circle touch internally then distance between their centre will be R-r(R>r)=25-15 =10
for externally touching circle R+r=25+15=40

When two circles touch each other, the two centers and the point of contact are all on one straight line.

If the two circles are touching each other externally, then
the distance between centers = sum of radii = 15+25 = 40 cm

If one circle touching the other from inside of the circle, then the distance is difference of radii : 25-15 = 10 cm.

no2: nice one......

sonali25: diameter are given so we have to take out radius first
