A belt is drawn tightly around three circles of radius 10 cm each, as shown*. What is the length of the belt? Please express your answer in terms of pi?
(π).
* It's the 2nd image where the circles are shaped like a triangle!
The length of the belt = 60 + 20pi
Length of belt (first one) = 40 * 2 + pi * 20 = 80 + 20pi = ~142.83 cm
I suggest trying to connect the center of the circles and then drawing lines from those centers onto the belt. :))

You should be able to work it out from this pic.
