Question

radil of two circle are 10 cm and 6 cm find the distance between their centre. 1) when they touches internally. 2) when they touches externally​

Answer 1

Answer:

1. 4 cm

2. 16 cm

Step-by-step explanation:

1.Let the radii of two circles be R

1 and R 2 .

∴ R 1 =10 and R 2 =6

If two circles are touching internally then the common point lies on the line joining their centres.

Therefore, distance between their centres is R1 −R2=10−6=4

2. The radii of the circles are 10cm and 6cm.

if two circle are touching internally then the common point lies on the line joining their centres.

R1 =10

R2=6

hence, Distance between their centre=

10cm +6cm

Hence,16cm
