To substitute the given values into the formula and solve for the unknown variable, follow these steps:
Step 1: Write down the given formula:
C + 2πr
Step 2: Replace the variable C with its given value:
40.8 + 2πr
Step 3: Now, you need to find the value of the variable r. Since the equation contains only one variable, you can isolate r by rearranging the equation.
Step 4: Subtract the constant term on the left side of the equation (40.8) from both sides:
2πr = C - 40.8
Step 5: Divide both sides of the equation by 2π to isolate r:
r = (C - 40.8) / (2π)
Step 6: Substitute the value of C (40.8) into the equation:
r = (40.8 - 40.8) / (2π)
Step 7: Simplify the equation:
r = 0 / (2π)
r = 0
Therefore, the value of r is 0.
