Question

How do you find Radius with just the circumference? An Equation Would be
Preferred. Thanks

Answer 1

answer:

c =

$2\pi r$

or

$\pi \: d$

Answer 2

Answer:

To find the radius with just the circumference is with this formula:

R = C ÷ (2 × π)

Or  just divide the circumference by 2 times pi.

Here's an example:

The circumference is 26

R = C ÷ (2 × π)

R = 26 ÷ (2 × 3.14)

R = 26 ÷ 6.28

R = 4.140127388535032‬ or 4.1

Hope this helped
