How to find the height of the cylinder?
To measure the height of the cylinder is taught in school geometry lessons. But outside the school, this knowledge can be useful in practice, for example, how to measure the height of a water tank. So, height is the distance from the highest point of the object to the bottom. If you can not measure it, you can find the formula. That is, if the cylinder is so high that there is no such ruler.
There is no doubt that we all remember from school years how to find the height of a cylinder, the formula looks like this: H = V / πR ^ 2 or 4V / D ^ 2.
To decipher the formula is simple:
- V is the volume of the cylinder;
- π – 3,14;
- R is the cylinder radius;
- D is the diameter.
That is, it turns out that if you divide the volume by the area of the base, you get the height of the cylinder.
You can do it easier. To do this, we have to calculate the lateral surface area of the required cylinder. This is easy to do by the formula: S = 2πRH. Slightly changing the formula, we get: H = S / 2πR.
Thus, there are already two methods that have helped to remember how to find the height of the cylinder.
