tree pipes of diameter 1 m are held together by a taut metal band as shown. Find the length in meters, of the metal band.

Answer 1

Join the centres and you will have an equilateral triangle with sides 1 m
Also the band will form 3 arcs , each of 120°.
So the band covers the entire distance around the circle, that is, its circumference.
Notice that if you complete the rectangle, we know the long side is 1 m

total distance = 2π(.5) + 3(1)
= (π+ 3) m

Answer 2

WRONG:)
