Step-by-step explanation:
First you need to know that A=πr^2
And the equation to find the diameter is d=2r
So, the equation is d=2√A/3.14
A is 314, so 314 divided by 3.14 is 10
So all that's left is d=2*10
And the diameter is 20 feet.
The diameter of the circular pool is 20 feet.
What is the diameter of the pool?A circle is a bounded figure which points from its center to its circumference is equidistant. The diameter is two times the value of the radius.
The first step is to determine the radius of the pool; Radius = √Area of a circle /π
Where :
π = pi = 22/7R = radius√314/3.14 = 10feet
Diameter 10 x 2 = 20 feet

A department store's customer parking lot has 4 rows with an equal number of parking spots in each row. The lot also has 15 parking spots for store employees. If c cars can be parked in each of the 4 main rows of the parking lot, what is the expression for the maximum number of cars that can be parked in the parking lot?
15c − 4
c(15 − 4)
4c + 15
4(c + 15)
The expression for the maximum number of cars that can be parked in the parking lot is:
4c+15
Step-by-step explanation:As there are a total of 4 rows.
and If c cars can be parked in each of the 4 main rows of the parking lot then the total number of cars that are parked in all the rows are:
4c
Also, 15 parking spots are for store employees.
Hence, the maximum number of cars that can be parked is represented by the expression as:
4c+15

Please older brother is 4 3/4 feet tall lien is 1/3 foot shorter than his brother how old how tall is Leon
Answer: Leon is 53/12 feet tall (4 5/12)
Step-by-step explanation:
Hi, to answer this question we have to subtract the height difference (1/3 ) to the Older brother's height. (4 3/4).
Mathematically speaking:
4 3/4 -1/3 = (4x4+3)/4 -1/3 = 19/4 -1/3 = 57/12-4/12 = 53/12 feet
Leon is 53/12 feet tall (4 5/12)

find the next 3 terms of the following sequence 22 21 18 13 6
The next 3 terms of the sequence 22, 21, 18, 13, 6 are 2, -3, and -8.
Explanation:The next 3 terms of the sequence 22, 21, 18, 13, and 6 can be found by analyzing the pattern in the sequence. The difference between each term is decreasing by 1 each time. So, the next difference would be 5 - 1 = 4. Subtracting 4 from 6 gives us 2. Therefore, the next term in the sequence is 2. Repeating this process, we can find the following terms: 2, -3, and -8.

1. A room is in the shape of a rectangle. The width of the room is 2 feet longer than two thirds the length. If the room is 33 feet long, what is the area?
To calculate the area of the rectangular room with a length of 33 feet and width that is 2 feet longer than two thirds of its length, we first find the width to be 24 feet and then multiply it with the length to get the area of 792 square feet.
Calculating the Area of a Rectangle
The question involves finding the area of a rectangular room given the length and a relationship between the length and width. The room is 33 feet long and the width is stated to be 2 feet longer than two thirds of the length. First, we determine the width by using the length to find two thirds of it and then adding 2 feet:

If a bookshelf is 28 1/8 inches long,how many 1 7/8 inch thick books will it hold?
Answer: Bookshelf can hold 15 books.
Step-by-step explanation:
Given : The length of the book shelf = [tex]28\dfrac{1}{8}[/tex] inches
In improper fraction , [tex]28\dfrac{1}{8}=\dfrac{8(28)+1}{8}=\dfrac{225}{8}[/tex]
i.e. Length of the book shelf = [tex]\dfrac{225}{8}[/tex] inches
Similarly, Thickness of a book = [tex]1\dfrac{7}{8}=\dfrac{8(1)+7}{8}=\dfrac{15}{8}[/tex] inches
Now, the number of books the shelf can hold = Length of the bookshelf ÷Thickness of a book
[tex]=\dfrac{225}{8}\div\dfrac{15}{8}\\\\=\dfrac{225}{8}\times\dfrac{8}{15} \\\\=\dfrac{225}{15}=15[/tex]
Hence, the bookshelf can hold 15 books.
