A 20-sided regular polygon has an angle measure represented as 3gº.

The value of g in the 20 sided regular polygon is 54.

<h3>How to find the angles of a regular polygon?</h3>

If all the polygon sides and interior angles are equal, then they are known as regular polygons.

The polygon given is a 20 sided regular polygon and the measure of each angle is 3g degrees.

Therefore, let's find g.

The sum of interior angles of a 20 sided polygon is as follows:

180(n - 2) = 180(20 - 2) = 180(18) = 3240

Therefore,

each angle = 3240 / 20 = 162

Hence,

162 = 3g

g = 162 / 3

Therefore,

g = 54

The Sunny Days Apartment building has a cylindrical, above ground pool in the yard. The radius of the pool is 1.5 times its heig

dezoksy [38]

Answer:

5.54 feet.

Step-by-step explanation:

Let h be the height of the pool and r be the radius of the pool.

We have been given that volume of cylindrical pool in Sunny Days Apartment building is 1200 cubic feet.

We have been given that the radius of the pool is 1.5 times its height. We can represent this information in an equation as:

$r=1.5*h...(1)$

$\text{Volume of cylinder}=\pi r^2h$

Substituting equation (1) in volume formula we will get,

$\text{Volume of cylindrical pool}=\pi (1.5h)^2*h$

Substituting the given volume of pool in formula we will get,

$1200=\pi (1.5h)^2*h$

$1200=\pi*2.25*h^2*h$

$1200=\pi*2.25*h^3$

Let us divide both sides of our equation by 2.25 pi.

$\frac{1200}{2.25\pi}=\frac{\pi*2.25*h^3}{2.25\pi}$

$169.7652726=h^3$

Let us take cube root of both sides of our equation.

$\sqrt[3]{169.7652726}=h$

$5.537=h$

$h=5.537\approx 5.54$

Therefore, the height of the pool is approximately 5.54 feet.
