Asked by Manav
A thin plastic band 50 cm long is used to tie seven plastic pipes together. What is the radius of the pipe?
The shape is a hexagon but not vertices but curved.
My solution was , you get an eqilateral triangle with side 3 r
3 r = 50/6
r = 50/6/3
= 2.73
But the text book answer is 25/(pi+6)

25 / ( pi + 6 ) =
25 / ( 3.1415926535 + 6 ) =
25 / 9.1415926535 =
2.734753226
approx. = 2.73
What is problem?

I see pi in Bosnian's calculations.

Where do you get the equilateral triangle with sides 3r from?
