Question

(i) Two circles with radii 3.5 cm and 2.5 cm touch each other internally. Find the
distance between their centres.​

Answer 1

Answer:

1cm

Step-by-step explanation:

Draw two circles that touch each other at a point. Mark the centers. Draw the radius of the smaller circle and then through it the radius of the larger one. Now, the radius of the smaller circle forms a part of the radius of the larger circle. Thus the required distance = 3.5-2.5=1
