Solution

To solve the formula C=2πr for the variable r, you need to isolate r. Here are the steps:

  1. Start with the original formula: C = 2πr

  2. To isolate r, you need to get rid of 2π on the right side of the equation. You can do this by dividing both sides of the equation by 2π: C/2π = r

So, the formula solved for the variable r is r = C/2π.
