Question

Rearrange the formula C = 2πr for r.
A r = 2πCr = 2πC
B r =
π


r = C 2 π
C r =
π


r = 2 C π
D r =
π

Answer 1

To rearrange the formula \( C = 2\pi r \) for \( r \), you need to isolate \( r \).

Starting from the equation:

\[
C = 2\pi r
\]

To find \( r \), divide both sides by \( 2\pi \):

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

None of the options you provided seem to match this correctly. The correct answer should be:

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