\begin{aligned} A &= \pi (R^2 - r^2) \\ &= \pi ((0.1\,\text{م})^2 - (0.06\,\text{م})^2) \\ &= ?\,\text{m²} \end{aligned}
\begin{aligned} w &= R - r \\ &= (0.1\,\text{م}) - (0.06\,\text{م}) \\ &= ?\,\text{م} \end{aligned}
\begin{aligned} C_R &= 2\pi R \\ &= 2\pi (0.1\,\text{م}) \\ &= ?\,\text{م} \end{aligned}
\begin{aligned} C_r &= 2\pi r \\ &= 2\pi (0.06\,\text{م}) \\ &= ?\,\text{م} \end{aligned}
