Answer 1

• Surface Area = 125.6 square units

,

• Volume= 20.6 cubic units

Step-by-step 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:

`\text{Total Surface Area}=2\pi r(r+h)`

Substitute the given values:

`\begin{gathered} \text{TSA}=2*3.14*2(2+8) \\ =2*3.14*2*10 \\ =125.6\text{ square units} \end{gathered}`

Volume

The volume of a cylinder is found using the formula:

`\text{Volume}=\pi r^2h`

Substitute the given values:

`\begin{gathered} \text{V}=3.14*2^2*8 \\ =20.56\text{ cubic units} \\ \approx20.6\text{ cubic units} \end{gathered}`
