[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]

B) r = C /2π

Step-by-step explanation:

C = 2πr

Divide each side by 2π

C/ 2π = 2πr/ 2π

C/ 2π = r

B) r = C/2π

Step-by-step explanation:

C = 2π × r

r = C/2π

B) r= c/2[tex]\pi[/tex]

Step-by-step explanation:

To isolate r, divide 2[tex]\pi[/tex] on both sides

c = 2[tex]\pi[/tex]r

-- --

2[tex]\pi[/tex] 2[tex]\pi[/tex]

c/2[tex]\pi[/tex]=r

Hope this helps! :)

If this is the formula for Circumfrence the formula should read C=2[tex]\pi[/tex]r₂
