Answer:

2.8cm

Step-by-step explanation:

First, convert 1m into cm:

1m * 100 = 100

Divide the length of the coil by the pieces of wire:

100 ÷ 3.6 = 27.777

= 27.8

Round down as a remainder means that a piece of wire cannot be cut:

27.8 = 27 remainder 0.8

Now multiply the 0.8 by 3.6:

0.8 * 3.6 = 2.88

Meaning the length of the coil left over is 2.8cm

Hope this helps!
