S = 2πrh + 2πr², for h

Mathematics
1 answer:
diamong [38]3 years ago
6 0

Answer:

Step-by-step explanation:

This is a literal equation, and for some reason, students literally freak out about solving them.  We will isolate h the same way we would if we were solving an equation for x.  In order to get the term with the h in it all by itself, we have to move everything else away from that term.  The 2πr² is added on the left, so we will move it by subtracting it from both sides, giving us

S-2\pi r^2=2\pi rh

Then we need to get the h alone.  Everything on the right side of the equals sign is multiplied together, so the "undoing" of multiplication is division, so that's what we'll do.  Divide everything away from the h:

\frac{S-2\pi r^2}{2\pi r}=h

which is choice C.

Answer:

4x - 15 = 3 \\ 4x = 3 + 15 \\ 4x = 18 \\ x =  \frac{18}{4}  \\ x =  \frac{9}{2}  \\  x = 4.5

Furkat [3]

Answer:

  Infinite solutions

Step-by-step explanation:

Equation M is equation P multiplied by 3. The equations are dependent, so any solution of one of them is also a solution of the other. There are an infinite number of (x, y) pairs that will satisfy either (both) equation(s).
