The surface area of the top open cylinder is 6810.149 sq.cm.

A cylinder is a three-dimensional solid that consists of two congruent surfaces (bases) and one lateral surface.

Surface area of a cylinder = Base area + Lateral area

Base area of a cylinder = 2 × π × r²

Lateral area of a cylinder = (2 × π × r) × h

Therefore, here base area of a cylinder = 2× π × 12²

                                                                  = 5837.27 sq.cm.

And, lateral area of a cylinder = (2 × π × 12) × 2

                                                  = 972.8784 sq.cm.

Therefore, total surface area of a cylinder = 5837.27 + 972.8784

                                                                      = 6810.149 sq.cm.

Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

Answer: 6.4 hours

Step-by-step explanation:

Hi, to answer this question we have to write an equation for each case:

Happy paws: the cost is equal to the fixed charge (19) plus the product of the charge per hour (3.50) and the number of hours (h).

Happy Paws Cost = 19+3.50h

Woof Watchers: the cost is equal to the fixed charge (11) plus the product of the charge per hour (4.75) and the number of hours (h).

Woof Watcher Cost = 11+ 4.75h

Since both costs must be equal:

Happy Paws Cost =Woof Watcher Cost

So:

19+3.50h = 11+ 4.75h

Solving for h:

19-11 = 4.75h-3.50h

8 = 1.25h

8/1.25 =h

h = 6.4 hours

Step-by-step explanation:

y-intercept: (0,1)

rate of change: 2/3

Y-intercept: I found this because the y-intercept is when x=0, and where the line crosses through the y-axis.  So, we can see that the y-intercept is (0,1)

Rate of change: The rate of change is another word for slope, or rise/run, so we can see, from point (0,1), that the rise is 2 units up and 3 units to the right to another point where the line crosses a whole number point.

Step-by-step explanation: :) Remember, the radius is just half of the diameter. So if the Diameter is 18, the radius is 9.

Step-by-step explanation:

The difference beteen 9.2 ounces and 8.1 ounces is  1.1 ounces

   and the difference in price is   .49

       so 1.1 ounces cost .49

           $ .49 / 1.1 oz = $  .445  per ounce

Then Reid's bowl should cost   7.8 oz  * $ .445 / oz = $3.47

Answer:

Step-by-step explanation:

To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.

Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.

The sum of the parts in the ratio is 8x + 5x + 2x = 15x.

We know that the total number of fruits is 120. Therefore, we can set up the following equation:

15x = 120

To solve for x, we divide both sides of the equation by 15:

x = 120 / 15

x = 8

Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:

Number of bananas = 2x = 2 * 8 = 16

So, there are 16 bananas in total.

We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

As we know distance = rate*time

Aircraft carrier:

time is 13 hours, 7 hours before container ship left then the 6 hours container traveled.

Let s be speed of aircraft carrier

--> d = 13s

Container ship:

time is 6 hours

speed is 5 km/h slower, so s-5

--> d = 6(s-5)

Since they are going in opposite directions, add up the distances to find how far apart they are

--> 13s + 6(s-5) = 540

Now solve for s-

--> 13s +6s -30 = 540

--> 19s = 570

--> s = 30

Aircraft carrier was traveling at 30 km/h and container ship 25 km/h
