Answer:
[tex]\frac{C}{2\pi }=r[/tex]
Step-by-step explanation:
[tex]C=2\pi r[/tex]
WE need to solve for 'r'. Our aim is to get 'r' alone
2πr mean 2 times pi times r
To remove 2π we do opposite operation
Opposite operation of multiplication is division.
To remove 2π , divide both sides by 2π
[tex]\frac{C}{2\pi }=\frac{2\pi r}{2\pi}[/tex]
Now simplify it
[tex]\frac{C}{2\pi }=r[/tex]
