Vedclass · Answer

(B) $5$-rupee coin is shaped like a thin cylinder.The total surface area $(TSA)$ of a cylinder with radius $r$ and height $h$ is the sum of its curved surface area and the areas of its two circular bases.$TSA = 	ext{Curved Surface Area} + 2 	imes 	ext{Area of circular base}$$TSA = 2 \pi r h + 2 \pi r^2$By taking $2 \pi r$ as a common factor,we get:$TSA = 2 \pi r(r + h)$Therefore,the correct formula is $A = 2 \pi r(r + h)$.

The $TSA$ (Total Surface Area) of a $5$-rupee coin is given by the formula $\ldots \ldots \ldots . .$
