Solve for h S=2πr2+2πrh
Vaselesa [24]

Answer:

<h2>h = \frac{S - 2\pi r ^{2} }{2\pi r}</h2>

Step-by-step explanation:

S = 2πr² + 2πrh

To solve for h move 2πr² to the other side of the equation

That's

2πrh = S - 2πr²

Next divide both sides by 2πr in order to isolate h

That's

<h3>\frac{2\pi rh}{2\pi  r}  =  \frac{S - 2\pi r ^{2} }{2\pi r}</h3>

We have the final answer as

<h3>h = \frac{S - 2\pi r ^{2} }{2\pi r}</h3>

Hope this helps you

(Brainliest for correct answer) Use the above graph to answer the following question. A move from point S to point U indicates
rusak2 [61]
The point s is where the suppl curve and demand curve meet. Hence moving down to point U would indicate an increase in quantity demanded because a shift to the right on supply curve, ie moving down to point u from point s indicates an increase in supply so that means an increase in quantity demanded. If it were to move the other way, ie to the left, then it would show a decrease in supply and a decrease in quantity demanded.
Hope this helps! Any questions please just ask! Thank you so much!!
