To solve the formula \( A = 2\pi r + h \) for \( r \), follow these steps:

1. Start with the original equation:
\[
A = 2\pi r + h
\]

2. Subtract \( h \) from both sides to isolate the term with \( r \):
\[
A - h = 2\pi r
\]

3. Now, divide both sides by \( 2\pi \) to solve for \( r \):
\[
r = \frac{A - h}{2\pi}
\]

Therefore, the solution for \( r \) is:
\[
r = \frac{A - h}{2\pi}
\]
