A cylindrical swimming pool has a diameter of 16 feet and a height of 3 feet. How many gallons of water can the pool contain? Ar

kiruha [24]

Answer:

The pool can contain 4521.6 gallons of water.

Step-by-step explanation:

Given:

The diameter of the cylindrical swimming pool = 16 feet.

And the height of the cylindrical swimming pool = 3 feet.

(1 ft³ = 7.5 gallons)

Now, to find the gallons of water the pool can contain.

So, we find the radius first:

Radius (r) = $\frac{Diameter}{2}$ = $\frac{16}{2} =8\ feet.$

Height (h) = 3 feet.

Now, to get the volume of swimming pool which is cylindrical in shape by putting formula (using the value of π = 3.14):

$Volume=\pi r^2h$

$Volume=3.14\times 8^2\times 3$

$Volume=3.14\times 64\times 3$

$Volume=602.88\ feet^3.$

Thus, getting the volume of pool 602.88 feet³.

As, given 1 ft³ = 7.5 gallons.

Now, to get the gallons of water the pool can contain we multiply the volume of pool by 7.5:

$602.88\times 7.5$

$=4521.6\ gallons.$

Therefore, the pool can contain 4521.6 gallons of water.

Write an equation of the line below

Kazeer [188]

Answer:

y=-1/3x+1

Step-by-step explanation:

The slope of this line is negative, and is equal to rise over run.

To find slope, count the number of spaces it has moved down or up, and then the number of spaces it has moved left or right.

The y intercept is represented by +1, and is where the line crosses the y axis.

Hope this helps!

Identify the variable that is continuous data used discretely. Select all that apply. There are 3 bugs. The bugs are red, yellow

Nata [24]

Answer:

The age of each bug

Step-by-step explanation:

Discrete variables are variables which are counted and can only take on whole number values such as 1, 2, 3...,. For example, the number of students in a class; the number of legs of a spider.

Continuous variables are variables that are measured and can take on a whole range of values such as 1.0, 1.1, 1.2...,. For example, the wingspan of a bug, the length of leaves; the exact age of students in a class.

Though age is a continuous variable if the exact age is required as it can take up a wide range of values such as 2.5 years; 2.3 years, 5.8 days etc,. However, in some instances, it can be rounded up to whole number values in years, months, weeks or even days.

For example, the age of a bug in days could be 1 day, 2 days, or 14 days.

The age of a student who is 12.2 years can be given as 12 years.
