Question

Two circles of radii 5.5 cm and 3.3 cm respectively touch each other. What is the distance between their centers?Choose the correct alternative.
(A) 4.4 cm
(B) 8.8 cm
(C) 2.2 cm
(D) 8.8 or 2.2 cm

Answer 1

HEY BUDDY....!!!

HERE'S THE ANSWER...

_______________________

▶️ We know . radius is a straight line from centre touching a point on it's circumference..

▶️ If both the circles are touch each other then the speration b/w their centres if sum of their radius ...

So ,

⏺️rad 1 = 5.5 , rad 2 = 3.3

=> Distance = rad 1 + rad 2

=> Distance = ( 5.5 + 3.3 )cm

=> Distance = 8.8cm


▶️ HENCE correct option is ( B )..

HOPE HELPED..

Answer 2

Answer:

D)8.8 or 2.2 cm

Step-by-step explanation:

we don't know whether the circles are touching each other at externally or internally.

so, if the circles are touching each other externally then,

r1 + r2

=5.5+3.3

=8.8 cm

or if the circles are touching each other internally then,

r1 - r2

=5.5-3.3

=2.2 cm

therefore, option D is correct. i.e, 8.8 or 2.2 cm
