Answer:
\(\frac{C}{2\pi }=r\)
Step-by-step explanation:
\(C=2\pi r\)
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
\(\frac{C}{2\pi }=\frac{2\pi r}{2\pi}\)
Now simplify it
\(\frac{C}{2\pi }=r\)
