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: $24\pi\text{ units}^2$

Step-by-step 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 = $24\pi\text{ units}^2$
