Sorry. Please check the correct answer below.

\begin{align*} &\phantom{=} 14+\frac{1}{2}\times 2 \times \pi \times r + \frac{30}{360}\times 2 \times \pi \times r_1 \\ &= 14+\frac{1}{2}\times 2\times \frac{22}{7}\times 7 + \frac{1}{12}\times 2 \times \frac{22}{7} \times 14 \\ &= 14+22+\frac{22}{3} \\ &= 43\frac{1}{3} \text{ cm} \end{align*}

$43\frac{1}{3}$

Yay! Your are right.
