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.

A model of an Egyptian pyramid has a slant height of 18 centimeters and a 15-centimeter square base. What is the surface area o

Angelina_Jolie [31]

Answer:

here is an example to guide you

Step-by-step explanation:

To find how much paper for the model, you will use the formula for area of a square and area of a triangle.

A = bh

7.2 x 7.2

A = 51.84 cm²

A = 1/2bh

1/2 x 7.2 x 6

A = 21.6 cm²

21.6 cm² x 4 = 86.4 cm²

86.4 + 51.86=138.3

You will need 138.3 cm² of paper.
