Question

the radii of circle touching internally are 3.5cm and 1.5cm . find the distance between their centers​

Answer 1

ANSWER:

2cm

STEP BY STEP EXPLANATION:

it is given that 2 circles having radii 3.5cm and 1.5 cm touch each other internally.

The distance between their centres of the circle touching internally is equal to the difference of their radii

Thus, distance between their centres is =(radius of bigger circle)- (radius of smaller circle).

=3.5 - 1.5

=2
