Question

Find the surface area of a cylinder with a height of 8 m and a base radius of 4 m.Use the value 3.14 for π, and do not do any rounding.Be sure to include the correct unit.

Answer 1

Explanation

We are given the following:

`\begin{gathered} height=8m \\ radius=4m \\ \pi=3.14 \end{gathered}`

We are required to determine the surface area of a cylinder. This can be achieved by using the formula:

`\begin{gathered} Area=2\pi r(r+h) \\ Area=2*3.14*4(4+8) \\ Area=2*3.14*4*12 \\ Area=301.44m^2 \end{gathered}`

Hence, the answer is 301.44m².
