Question

Radii of two circles are 6.3 cm and 3.6 cm. State the distance between their centers if -

they touch each other internally.

Answer 1

Radius of bigger circle = 6.3 cm

and of smaller circle = 3.6 cm

Two circles are touching each other at P internally. O and O’ are the centers of the circles. Join OP and O’P

OP = 6.3 cm, O’P = 3.6 cm

OO’ = OP - O’P = 6.3 - 3.6 = 2.7 cm
