Question

two circles of radii 4.4 cm and 7.7 cm touch each other externaly what is distance between their centers.?​

Answer 1

Step-by-step explanation:

distance between the centers if two circles which touch each other externally is :

R1 + R2

d = 4.4 + 7.7

d = 12.1 cm

Answer 2

Answer:

radii of 1st circle = 4.4 cm

radii of 2nd circle =7.7cm

distance between their centers = 1st circle radii +2nd circle radii

= 4.4 +7.7 = 12.1 cm
