Question

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

Answer 1

`\begin{gathered} \text{Surface area = 1507.20 cm}^2 \\ \text{Volume = 3617.28cm}^3 \end{gathered}`

Step-by-step explanation:

radius = r =12cm

height = h =8 cm

π = 3.14

`\text{Surface area of cylinder = 2}\pi r^(2)\text{ + }2\pi rh\text{ }`
`\begin{gathered} \text{Surface area of cylinder = (2}*3.14*12^2)\text{ + }(2*3.14*12*8) \\ S\text{urface area of cylinder = 904.32 + 602.88} \\ \text{Surface area of cylinder = }1507.20cm^2 \end{gathered}`

Volume of a cylinder = πr²h

`\begin{gathered} \text{Volume of cylinder = 3.14}*12^2*8 \\ \text{Volume of cylinder = }3617.28cm^3 \end{gathered}`
