The radius of the cylinder is = 9
The ends of the rollers are surrounded by metal strip. The metal strip goes round the circle. That is the circumference of the circle.
C = 2πr = 2π*9 = 18π cm.
Length of metal sheet on one of the circle = 18π cm.
For the 3 rollers = 18π *3 = 54π cm. Using π ≈ 3.14
Length = 54π ≈ 54*3.14 ≈ 169.56 cm
Therefore length for the 3 metal strips = 54π ≈ 169.56 cm
The net sales is $46,0000
<h3>What is Gross sales?</h3>
Gross Sale is the total of goods sold to the customers during a period. The goods can be sold on a cash basis or an account basis. The net sale is calculated as the gross sales minus sales returns and allowances and discounts on the sale.
Given:
sales= $50,000
sales returns = $4000
Now,
Net Sale = Gross Sale - Sales returns and allowances
= $50,000 - $4,000
= $46,000
Hence, the net sales is $46,000

Answer:
- ornament area = 379.8 cm²
- paint needed: 114 bottles
Step-by-step explanation:
The surface area of one cone with slant height s and radius r is ...
SA = πr² +πrs = πr(r+s)
For the cone that is half an ornament, the surface area is ...
SA = (3.14)(4.2 cm)(4.2 cm + 10.2 cm) = 189.9072 cm²
The area of one ornament is the area of two cones:
one ornament area = 2×189.9072 cm² ≈ 379.8 cm²
60 ornaments will be 120 cones, so will have a total surface area of ...
total area = 120(189.9072 cm²) = 22,788.864 cm²
__
If one bottle of paint will cover 201 cm², then the number of bottles of paint required is ...
(22788.864 cm²)/(201 cm²/bottle) ≈ 113.4 bottles
Answer:
The average speed of the 747 was of 580 miles per hour.
Step-by-step explanation:
We use the following relation to solve this question:
![v = \frac{d}{t}](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7Bd%7D%7Bt%7D)
In which v is the velocity, d is the distance and t is the time.
A small airplane flies 1015 miles with an average speed of 290 miles per hour.
We have to find the time:
![v = \frac{d}{t}](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7Bd%7D%7Bt%7D)
![290 = \frac{1015}{t}](https://tex.z-dn.net/?f=290%20%3D%20%5Cfrac%7B1015%7D%7Bt%7D)
![290t = 1015](https://tex.z-dn.net/?f=290t%20%3D%201015)
![t = \frac{1015}{290}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B1015%7D%7B290%7D)
![t = 3.5](https://tex.z-dn.net/?f=t%20%3D%203.5)
1.75 hours after the plane leaves, a Boeing 747 leaves from the same point. Both planes arrive at the same time;
The time of the Boeing 747 is:
![t = 3.5 - 1.75 = 1.75](https://tex.z-dn.net/?f=t%20%3D%203.5%20-%201.75%20%3D%201.75)
Distance of
, the velocity is:
![v = \frac{d}{t} = \frac{1015}{1.75} = 580](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7Bd%7D%7Bt%7D%20%3D%20%5Cfrac%7B1015%7D%7B1.75%7D%20%3D%20580)
The average speed of the 747 was of 580 miles per hour.
