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!
