# The circumference of a circle can be found using the formula c = 2r

## Answers

No its c=2piR

Cant use pi sybol

the answer is c: R=C/2pi

I can't do the pi simbol

C. r = C/2π

Step-by-step explanation:

[tex]r=C/(2\pi)[/tex]

Step-by-step explanation:

we know that

The circumference of a circle is equal to

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

where r is the radius of the circle

Solve for r------> means isolate the variable r

so

Divide by [tex]2\pi[/tex] both sides

[tex]C/(2\pi)=2\pi r/(2\pi)[/tex]

[tex]r=C/(2\pi)[/tex]

r equals StartFraction C Over 2 pi EndFraction

Step-by-step explanation:

we know that

The circumference of a circle is equal to

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

where

r is the radius of the circle

Solve for r

That means -----> isolate the variable r

Divide by 2π both sides

[tex]\frac{C}{2\pi}=\frac{2\pi r}{2\pi}[/tex]

Simplify right side

[tex]\frac{C}{2\pi}=r[/tex]

Rewrite

[tex]r=\frac{C}{2\pi}[/tex]

so

r equals StartFraction C Over 2 pi EndFraction

R=C/2(eliminate "2" from r by dividing both sides by 2)
