Question

If two circles of centre o and c with radii 2cm and 3 cm touch externally, what is the distance between their centre??

Answer 1

Answer:

5 cm

Step-by-step explanation:

radius 1+ radius 2

• 2+3

•5 cm

Answer 2

Answer:

The distance between the centers of the circles with centers o and c is 5 cm.

Step-by-step explanation:

• They have given that two circles with centers o and c and radii 2 cm and 3 cm touch externally.
• If two circles touch externally, the distance between their centers will be the sum of their radii.

Let the radius of the circle with center o be r1 = 2 cm

Let the radius of the circle with center c be r2 = 3 cm

Therefore the distance between their centers is given by

                                      = r1 + r2 = 2 + 3 = 5 cm

Hence the distance between the centers of given circles is 5 cm.
