Question

3.
distance between their centres.
If radii of two circles are 4 cm and 2.8 cm. Draw figure of these circles
touching each other - (i) externally (ii) internally.​

Answer 1

Answer:

Distance between the centres =4cm−2.8cm=1.2cm

Step-by-step explanation:

• The radii of the two circles are 4cm and 2.8cm.
• If two circles touch each other externally, then the distance between their centres is equal to the sum of the radii.
• Distance between the centres =4cm+2.8cm=6.8cm
• If two circles touch each other internally, then the distance between their centres is equal to the difference of the radii.
• Distance between the centres =4cm−2.8cm=1.2cm
