Question

find the lateral surface area of the pipe in square meters

Answer 1

Answer:

287.64 square meters

Explanation:

The tube is in the shape of a cylinder with dimensions:

• Diameter=8.4 meters

,

• Height = 10.9 meters

The lateral surface area of any cylinder is obtained using the formula:

$\text{Lateral Area}=2\pi rh^{}$

First, recall that:

$\text{Diamter}=2r$

Therefore:

$\begin{gathered} \text{Lateral Area}=2r\times\pi\times h^{} \\ =8.4\times\pi\times10.9 \\ =287.64\; m^2 \end{gathered}$

The lateral surface area of the pipe is 287.64 square meters (correct to the nearest hundredth).
