A company is going to make a water tank in the shape of a cylinder. As shown below, the tank will have a height of 2ft and a radius of 5ft. The tank will be made from metal (including its top and bottom). Suppose the total cost of the metal will be 8572.20. How much will the metal cost per square foot? Use 3.14 for pi, and do not round your answer.
Please give an understandable step-by-step explanation. Thank you !!
Answer:
$39 per square foot.
Step-by-step explanation:
The cylinder has a height of 2 feet and a radius of 5 feet.
The total cost of the metal will be (assuming US dollars) $8572.20.
And we want to determine the cost per square foot.
First, we can find the surface area of the cylinder. The surface area for a cylinder is given by the formula:
[tex]SA=2\pi r^2+2\pi rh[/tex]
Where r is the radius and h is the height.
Since the radius is 5 feet and the height is 2 feet and using 3.14 for π, the surface area is:
[tex]SA=2(3.14)(5)^2+2(3.14)(5)(2) =219.8\text{ feet}^2[/tex]
Therefore, to find the cost of metal per square foot, we can divide the total cost over the amount of surface area. Hence:
[tex]8572.20 / 219.8= \$ 39 \text{ per square foot}[/tex]
So, the metal costs $39 per square foot.

of all the songs on a playlist, 1/3 are rock, 1/8 are dance, and the rest are country. what fraction of all the songs on the playlist are country?
Answer:
13/24
Step-by-step explanation:
First, it would be easier to find the common denominator of 1/3 and 1/8. The easiest way to do that is to do 3x8=24. This means the common denominator is 24 and so we must convert the fractions so they have this denominator.
1/3 --> 8/24
1/8 --> 3/24
Now, we can simply add these fractions together to find out the fraction of songs that are NOT country songs.
8/24 + 3/24 = 11/24 songs are not country songs.
To find out the fraction of songs that are country, simply do 1 (or 24/24) take away 11/24.
24/24 - 11/24 = 13/24 songs are country songs.

You have 24 coins valued at $3.00. Some of the coins are dimes and some are quarters. Find the number of each coin that you have.
Answer:
10 Quarters and 5 dimes
Step-by-step explanation:
10 Quarters = $2.50
5 dime = $0.50
Answer:
20 dimes and 4 quarters
Step-by-step explanation:
So, a dime is 10 cents and a quarter is 25
So, let's say you have x dimes and y quarters
X+Y=24 (total amount of coins)
Also,
10x+25y= 300 (cents)
I just put the 3 dollars into cents
Now, you have a system of equations and we should solve it:
X+y=24 ----x=24-y
10x+25y=300
So substitute x in the 2nd equation
10(24-y)+25y=300
240-10y+25y=300
240+15y=300
15y=60
y=4
Now that you know the amount of quarters, you can just say that you will have 20 dimes since 24-4=20
So, 4 quarters and 20 dimes
Check:
20 dimes=2 dollars
4 quarters= 1 dollar

What is the measure of JK?
A. 35
B. 55°
C. 145°
D. 125°
Answer:
125 degrees.
Step-by-step explanation:
L is the midpoint of NK so the arcs NM and Mk are equal.
So MK = 55 degrees and the arcs JN and JK are equal
Therefore
JK =
(360 - 2*55)/2
= (360 - 110) / 2
= 250 /2
= 125 degrees.
