Detailed Solution

Given
Diameter D=14cm
Height H=13cm
Thus, its radius r=7 cm
Height of cylindrical part,

(h) = 13 - 7 = 6 cm

Inner surface is of the vessel = CSA of cylindrical part + CSA of hemispherical part

= 2 π rh + 2 π r^{2}

Inner surface area of vessel,

= 2 \times \frac{22}{7} \times 7 \times 6 + 2 \times \frac{22}{7} \times 7 \times 7

\begin{matrix} = 44 (6 + 7) \\ = 44 \times 13 \\ = 572 {cm}^{2} \end{matrix}

Option 1 is correct.
