Question

C = 2 * π * r, solve for r.

a) r = C / 2π
b) r = C / π
c) r = C / 2
d) r = C / 4π

Answer 1

To solve for r in the equation C = 2πr, divide both sides of the equation by 2π to isolate r.

Step-by-step explanation:

To solve for r in the equation C = 2Πr, we need to isolate r. Here are the steps:

1. Divide both sides of the equation by 2Π: r = C / (2Π)

So the correct answer is r = C / (2Π) (option a).
