Question

Find the lateral surface area of a cylinder whose radius is 1.2 mm and whose height is 2 mm.

Answer 1

`\textit{lateral area of a cylinder}\\\\ LA=2\pi rh~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=1.2\\ h=2 \end{cases}\implies LA=2\pi (1.2)(2)\implies LA\approx 15.08~mm^2`
