Answer:
• Surface Area = 125.6 square units
,
• Volume= 20.6 cubic units
Explanation:
From the given figure:
• The radius of the cylinder, r= 2
,
• The height of the cylinder, h = 8
Surface Area
The surface area of a cylinder is found using the formula:
[tex]\text{Total Surface Area}=2\pi r(r+h)[/tex]
Substitute the given values:
[tex]\begin{gathered} \text{TSA}=2\times3.14\times2(2+8) \\ =2\times3.14\times2\times10 \\ =125.6\text{ square units} \end{gathered}[/tex]
Volume
The volume of a cylinder is found using the formula:
[tex]\text{Volume}=\pi r^2h[/tex]
Substitute the given values:
[tex]\begin{gathered} \text{V}=3.14\times2^2\times8 \\ =20.56\text{ cubic units} \\ \approx20.6\text{ cubic units} \end{gathered}[/tex]
