Question

Find the lateral area of the cylinder .The lateral area of the given cylinder is _ M2(Round to the nearest whole number as needed .)

Answer 1

The lateral area of a cylinder is:

`LA=2\pi rh`

r is the radius

h is the height

For the given cylinder:

As the diameter is 4m, the radius is half of the diameter:

`r=(4m)/(2)=2m`

h=12m

`\begin{gathered} SA=2\pi(2m)(12m) \\ SA=48\pi m^2 \\ SA\approx151m^2 \end{gathered}`Then, the lateral area of the given cylinder is 151 square meters
