The radius of a cylindrical construction pipe is 2 ft. If the pipe is 17 ft long, what is its volume?
Use the value 3.14 for it, and round your answer to the nearest whole number.
Answers
Answer:
[tex]volume \: = \: \pi \times r {}^{2} \times length(height) \\ = 3.14 \times 2f \times 17ft \\ = 106.76ft {}^{3} [/tex]
Answer:
V = 106.76ft
Step-by-step explanation:
Cylinder Formulas in terms of r and h
Calculate the volume of a cylinder: V = πr2hCalculate the lateral surface area of a cylinder (just the curved outside)**: L = 2πrhCalculate the top and bottom surface area of a cylinder (2 circles): T = B = πr2Total surface area of a closed cylinder is: A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)In one hour a seamstress can sew 48 yards of material.

Consider a car rental for $42, plus $0.22 per mile driven. Which statements are correct?
A) This situation is modeled by a linear function.
B) If the car is driven 200 miles, the rental will cost $86.
C) If the car is driven 500 miles, the rental will cost $142.
D) This situation can be modeled by the function f(x) = 0.22x + 42.
E) This situation can be modeled by the function f(x) = (0.22)X + 42.
Answers
Answer:
a, b and d
Step-by-step explanation:
200 miles x 0.22 = 44$ + 42$= 86$
the equation would be f(x)= 0.22x + 42.

Jessica got fast food for lunch. Jessica paid 3.10 dollars on fries and 4.88 on the sandwich with a $10 bill. Jessica got a combo deal. What was the change from the purchase?
Answers
Answer:
$2.02
Step-by-step explanation:
If Jessica paid $3.10 for fries and $4.88 for the sandwich, we need to add these two values together to find the total cost of her entire meal.
3.10 + 4.88 = 7.98
Since Jessica paid with a $10 bill then we need to subtract the total from the bill in order to find the change that Jessica will receive from her purchase.
$10 - $7.98 = $2.02
Now we can see that Jessica will receive a total of $2.02 in change after making her purchase.

Scott's window store made a mosaic for the community center. The mosaic had an 8 × 8 array of different color square tiles. If each tile is 2 2/3 ft long, what is the area of the whole mosaic?
Answers
Answer:
455.1111 feet²
Step-by-step explanation:
Given that :
Array of mosaic = 8 * 8 color square tiles
Length of each tile = 2 2/3 feets long
The length of mosaic = length per tile * Number of array :
2 2/3 feets * 8 = 21.3333 feets
This corresponds to the side length of the mosaic
The Area of the whole mosaic:
Using the area of square formula = s²
Where, s = side length
s = 21.33333 ft²
s² = 21.33333²
s² = 455.1111²

On an island there are 7 cities each 2 of them connected by a direct road they are building a 8th city they also want it to connect with the other 7 existing cities how many roads will there be after they build the 8th city
Answers
Answer:
After the 8th city is built there will be 28 roads between the cities
Step-by-step explanation:
The given parameters are;
The number of cities initially on the island = 7 cities
The number of roads between each 2 cities = 1 road
Therefore, we have the number of roads between the 7 cities are;
7 cities taking 2 at a time = ₇C₂
[tex]_7C_2 = \dfrac{7!}{(7 - 2)!\cdot 2!} = 21[/tex]
The initial number of roads between the 7 cities = 21 roads
The number of roads, 'n' there will be after the 8th city is built is therefore;
[tex]n = _8C_2 = \dfrac{8!}{(8 - 2)!\cdot 2!} = 28[/tex]
The number of roads there will be after the 8th city is built, n = 28 roads.

christen has to run around the rectangle soccer field during practice. The soccer field measures 60 meters long by 45 meters wide. How far did christen run?
Answers
Answer:
210 m
Step-by-step explanation:
Perimeter is the distance around the outside of a two-dimensional shape.
Area is the space inside of a two-dimensional shape. We can also think of area as the amount of space a shape covers.
Christen ran around the soccer field, so she ran around the perimeter.
We can find the perimeter by adding all of the side lengths.
Perimeter=60 m+45 m+60 m+45 m
Christen ran 210m.
