Four pencils are held together with a band.
Each of the pencils diameter 10mm.
Find the length of the band in this position
Give your answer in terms of π.

Respuesta :

Answer:20πmm

Step-by-step explanation:

each pencil diameter=10mm

each pencil diameter=radius Of The band

Radius of band=10mm

Circumference of band=2 x π x radius

Circumference of band=2xπx10

Circumference of band=20π

The length of band is the circumference Of The band

There length of band is 20πmm
