GUYS I NEED HELP ASAP!!!<br><br> Help me solve ?

Shalnov [3]

Solution:

$$h=\frac{ A-2\pi r^2}{2\pi r }$

Given data:

$A=2\pi r^2+2\pi r h$

Let us determine what is h using given A.

$A=2\pi r^2+2\pi r h$

Subtract $2\pi r^2$ on both sides of the expression.

⇒ $A-2\pi r^2=2\pi r^2+2\pi r h-2\pi r^2$

⇒ $A-2\pi r^2=2\pi r^2-2\pi r^2+2\pi r h$

⇒ $A-2\pi r^2=2\pi r h$

Divide both sides of the expression by $2\pi r$ .

$$\frac{ A-2\pi r^2}{2\pi r }=\frac{2\pi rh }{2\pi r }$

$$\frac{ A-2\pi r^2}{2\pi r }=h$

$$h=\frac{ A-2\pi r^2}{2\pi r }$

Option C is the correct answer.

Hence $$h=\frac{ A-2\pi r^2}{2\pi r }$ .
