Question

Find the lateral area of the cylinder .The lateral area of the given cylinder is _ m2.

Answer 1

Lateral Surface Area of a Cylinder.

The lateral area of a cylinder means the curved surface area of the cylinder.

`\begin{gathered} \text{Curved Surface Area of a Cylinder = 2}\pi rh \\ \text{where r =}(diameter)/(2)=(8)/(2)=4m\text{ and h=16m} \end{gathered}`
`\text{Curves Surface Area =2}*(22)/(7)*4\text{ }*\text{ 16 =402.286 }\approx402.29m^2`
