How many complete rings can be made out of a straight piece of wire of length 23.595m if each ring has a perimeter of 1.1m?
Show workings
Perimeter of a ring = 2πr
1.1 = 2πr
r = 0.534m
Length of wire = 23.595m
Number of rings = Length of wire / Perimeter of a ring
Number of rings = 23.595 / 1.1
Number of rings = 21.445
Therefore, 21 complete rings can be made out of a straight piece of wire of length 23.595m if each ring has a perimeter of 1.1m.
