If you don’t mind I might need help on more than one question on this :)

radius = r =12cm
height = h =8 cm
π = 3.14
[tex]\text{Surface area of cylinder = 2}\pi r^{2}\text{ + }2\pi rh\text{ }[/tex][tex]\begin{gathered} \text{Surface area of cylinder = (2}\times3.14\times12^2)\text{ + }(2\times3.14\times12\times8) \\ S\text{urface area of cylinder = 904.32 + 602.88} \\ \text{Surface area of cylinder = }1507.20cm^2 \end{gathered}[/tex]Volume of a cylinder = πr²h
[tex]\begin{gathered} \text{Volume of cylinder = 3.14}\times12^2\times8 \\ \text{Volume of cylinder = }3617.28cm^3 \end{gathered}[/tex]
