A wooden article was made by scooping out a hemisphere from each end of a solid cylinder, as shown in the figure. If the height of the cylinder is 5…

\[\begin{aligned} \text { CSA of cylinder } & =2 \times \frac{22}{7} \times 2.1 \times 5.8 \\ & =76.56 \mathrm{~cm}^{2} \\ \text { CSA of two hemisphere } & =4 \times \frac{22}{7} \times 2.1 \times 2.1 \\ & =55.44 \mathrm{~cm}^{2} \end{aligned} \] Total Surface Area of article \(\displaystyle =76.56+55.44=132 \mathrm{~cm}^{2}\)
