Question : Three circles of radius 6 cm are kept touching each other. The string is tightly tied around these three circles. What is the length of the string?

Option 1: $36 + 12\pi\ \text{cm}$

Option 2: $36 + 18\pi\ \text{cm}$

Option 3: $24 + 36\pi\ \text{cm}$

Option 4: $36 + 20\pi\ \text{cm}$

Team Careers360 20th Jan, 2024

Correct Answer: $36 + 12\pi\ \text{cm}$


Solution :
The length of the string not in contact with the circle = $2r+2r+2r=6r=6\times6=36$
By symmetry, the angle swiped by the string on one circle = $120^\circ$
Length of the string touching circle = $\frac{2\pi r}{3}+\frac{2\pi r}{3}+\frac{2\pi r}{3}=\frac{6\pi r}{3} = 2\pi r$
$=2\pi
