Question

(NEED HELP!!!) WILL MARK BRAINLIETS! ATTACHMENT INCLUDED! NEED EXPLANATION.
A thin plastic band is used to tie the seven plastic pipes together. If the band is 50cm long, what is the radius of each pipe?

(Using geometry)

Answer 1

Imagine any three pipes that are connected by a line.

The length between them is the distance from one point of the wire to the other point. This length is 6r when r is the radius of the circles.

Now, this is the diameter of the whole outer figure formed.

Circumference = π d = 6πr = 50.

Now, find r.
