1.	Two circle touch each other internally. If the radius of the larger circle is 7cm and the distance between their centre is 4cm. Find the radius of the smaller circle.
Answer» Answer: Given : Radii of two circles who TOUCH each other INTERNALLY has radii of 7 CM and 4 cm. To find : Length of AB. Solution : This means that, length of BC = 4 cm and AC = 7 cm. Now we know that, AC - BC = AB Hence, 7 cm - 4 cm = AB 3 cm = AB. Hence length of distance between centers if two circles is 3 cm.

Answer:

Given : Radii of two circles who TOUCH each other INTERNALLY has radii of 7 CM and 4 cm.

To find : Length of AB.

Solution : This means that, length of

BC = 4 cm and AC = 7 cm.

Now we know that,

AC - BC = AB

Hence, 7 cm - 4 cm = AB

3 cm = AB.

Hence length of distance between centers if two circles is 3 cm.
