The distance between pencil centers on each side is 1 diameter, or 7mm.
At each corner there is a quarter-circle, so the entire length is
4*7 + π*7 = 7(4+π) mm
four pencils are held together in a square by an elastic band if the pencils are of diameter 7mm what is the length of the band in this position

Wow Its So Cul..Thanks
Thank you it was correct.
ok but what if it was 10mm?
if it was 10mm it would be 10(4+π)
thanks alot
What if the same elastic band holds 7 of the same pencil
The number of pencils touching the band is 6 using 60° for ©
2r+[©/360×2#r]
That is perimeter if a sector.
2r+[©/360×2#r]
That is perimeter if a sector.
Radius of pencil=7/2. Length of band=4*2d=8*7=56mm
