Answer:
--- radius
-- Length of the square
Step-by-step explanation:
Given

Solving (a): Find the radius (when it formed a circle).
The length of the wire represents the circumference (C) of the wire.
So, we have:

Make r the subject

Substitute 264 for C


Take
as 22/7




Solving (b): Find the side length (when it formed a square).
The length of the wire represents the perimeter (P) of the wire.
So, we have:

Make L the subject

Substitute 264 for P


Answer: true
Step-by-step explanation:
It's the first option, 3/23
5y+8
When you figure out what y is you plug it in and do PEMDAS.
But if it doesn't tell you what y is then the equation I wrote is the answer.
