Answer:

The height of the cylinder is 4x units.

Step-by-step explanation:

volume of a cylinder = nr^2h

n = 22/7

r = radius = x/2

Let illustrate with an example. If the diameter of a cylinder is 6 and the volume is 6^3 = 216. The radius = 6/2 = 3

n3^2 x h = 216

h = 216/9 = 24

so the height is 4 times the diameter

Area of the base = nr^2

1/2^2 x x = 1/4 pi x^2

Solve for n 50 points <br><br> a=p(1+r/n)^rn

Answer:

$n = \frac{r}{\sqrt[nt]{\frac{a}{p}} -1 }$

Step-by-step explanation:

$a=p(1+\frac{r}{n} )^{nt}$

$\frac{a}{p} =(1+\frac{r}{n} )^{nt}$

$\sqrt[nt]{\frac{a}{p}} =(1+\frac{r}{n} )$

$\sqrt[nt]{\frac{a}{p}} -1 =(\frac{r}{n} )$

$n = \frac{r}{\sqrt[nt]{\frac{a}{p}} -1 }$

[ Do not confuse, as there are 2 n's, one in subject and another as power. We can never make the power or in a root, the subject. In order to solve for n, we have to make the character "n", the subject. ]
