Rearrange the formula C = 2πr for r.

Rearrange the formula C = 2πr for r.

Answer:

\frac{C}{2 \pi}=r

Step-by-step explanation:

C=2πr

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
