The radius is given 3.5 ft and height is given 14 ft.

To find the surface area of cylinder,

Use the formula.

$S=2\pi rh+2\pi r^2$

Substitute the values.

$\begin{gathered} S=2\pi r(h+r) \\ S=2*3.14*3.5(14+3.5) \\ S=384.65ft^2 \end{gathered}$

The volume of cylinder is determined as

$V=\pi r^2h$

Substitute the values

$\begin{gathered} V=3.14*3.5^2*14 \\ V=538.51ft^3 \end{gathered}$

The surface area of cylinder is 384.65 sq.ft.

The volume of cylinder is 538.51 cubic feet.
