Answer

9.0 cm.

Work Step by Step

The plane surface has an infinite radius of curvature. Let this be surface 2. Use the lensmaker’s equation. $$\frac{1}{f}=(n-1)(\frac{1}{R_1}+\frac{1}{R_2})$$ $$\frac{1}{f}=(n-1)(\frac{1}{R_1}+\frac{1}{\infty})$$ $$\frac{1}{f}=\frac{ n-1}{R_1}$$ $$R_1=(n-1)f=(1.55-1)(16.3cm)=9.0cm$$
