Answer 1

Given:

A cylinder having radius 1.5 inches and a height of 3.25 inches

Required:

Estimate the number of square inches of tin required for its construction.

Step-by-step explanation:

To calculate the number of square inches of tin required for its construction we have to calculate the area of the lid and base and the curved surface then add them all.

`\begin{gathered} \pi r^2+\pi r^2+2\pi rh \\ \Rightarrow(22)/(7)*1.5^2+(22)/(7)*1.5^2+2*(22)/(7)*1.5*3.25 \\ =44.76769531\text{ in}^2 \\ =44.77\text{ in}^2 \end{gathered}`

Final Answer:

44.77 inches square
