Question

Find the total area for the cylinder with the given measurement. r = 2, h = 4 16 square units 20 square units 24 square units

Answer 1

`\bf \textit{total area of a cylinder}\\\\ A=2\pi r(h+r)~~ \begin{cases} r=radius\\ h=height\\ -----\\ r=2\\ h=4 \end{cases}\implies A=2\pi (2)(4+2)\\\\\\ A=24\pi`

Answer 2

Answer:
`24\pi\text{ units}^2`

Explanation:

We know that the total surface area of a cylinder is given by :-

`TSA= 2\pi r(r+h)` , where r = radius and h= height of cylinder.

Given : Height : h= 4 units

Radius = 2 units

Then, the total surface area of the cylinder is given by :-

`TSA= 2\pi 2(2+4)`

`\Rightarrow\ TSA= 2\pi (12)=24\pi\text{ units}^2`

Hence, the total area for the cylinder =
`24\pi\text{ units}^2`
