Question

A cylinder has a height of 6 in ches and a radius of 4 inches find the Volume and the Surface area

Answer 1

The surface area of a cylinder is given by:

`SA=2\pi r^2+2\pi rh`

And the volume by:

`V=\pi r^2h`

Where:

r = radius = 4in

h = height = 6in

so:

`\begin{gathered} V=(3.14)(4^2)(6) \\ V=301.44in^3 \end{gathered}`
`\begin{gathered} SA=2(3.14)(4^2)+2(3.14)(4)(6) \\ SA=100.48+150.72 \\ SA=251.2in^2 \end{gathered}`
