To find the volume of a pipe, use the formula V = Ah where A is the cross-sectional area and h is the height of the pipe. Substituting the values given, the volume of the pipe is 826.805 cm³.
The volume of the pipe can be calculated using the formula V = Ah, where A is the cross-sectional area and h is the height of the pipe. In this case, the cross-sectional area can be found using the formula for the area of a circle, A = πr². Given that the pipe has a diameter of 9 cm, the radius (r) is half of the diameter, which is 4.5 cm.
Substitute the values into the formulas to find the volume: A = π(4.5 cm)² = 3.142 x 20.25 cm² = 63.585 cm². Now, calculate the volume using V = 63.585 cm² x 13 cm = 826.805 cm³.

What are proportions?Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. The proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.
Let the total number of books be x.
Now, the ratio of fictional to nonfictional boos is 3:7
Total=3+7=10
So, 3/10 = 240/x
⇒3x=240×10
⇒3x=2400
⇒x=800
Therefore, the total number of books in the school library is 800.

Of all the species in the world, 4 44 out of every 5 55 are insects. What percentage of species are insects?
The percentage of insects is 80%.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of species = 555x
Number of insects = 444x
Now,
The percentage of insects.
= 444x/555x x 100
= 44400/555
= 80%
Thus,
The percentage of insects is 80%.

How is rate of change related to slope
They're pretty much the same thing but when you hear the word rate of change, your thinking of it more in the context of a word problem and interpreting what it means. So labels are pretty much the key difference.
So like slope is here is a random coordinate plane, here's random points or just tell me what the slope is whereas rate of change is like it's number of meters per minute or its number of miles per hour so rate of change means you're comparing two quantities but you have units or labels attached to it.
You're calculating it in the same way but when we say rate of change we're really being asked in the context what does it mean.

An airplane travels 780 miles in 4 hours. Make a table and graph to show the mileage for 2,8 and 12 hours. Is there a direct variation? Explain.
Answer:
Yes, there is a direct variation, where the constant is 195 miles\hr
Step-by-step explanation:
Consider the provided information.
An airplane travels 780 miles in 4 hours.
780 miles = 4 hours
Divide both the sides by 4.
780/4 miles = 4/4 hours
195 miles = 1 hours
we need to make a table and graph to show the mileage for 2,8 and 12 hours.
The required table is shown below:
hr Mileage (Miles)
2 2×195 = 390 miles
8 8×195 = 1560 miles
12 12×195 = 2340 miles
From the table we can observe that there is a direct variation, where the constant is 195 miles\hr
The graph of the table is shown below.
The graph is a line passing through the origin.

What are some alternative names for arithmetic operations?The addition is also known as the sum, subtraction is also known as the difference, multiplication is also known as the product, and division is also known as the factor.
let us assume that we subtract 98 from the number x.
∴ We are taking the difference of x and 98 we have to borrow 98 from that number x.
For example -: We have to subtract 98 from 299, here we will borrow 98 from 299 which is (299 - 98) = 101.

Look at the picture. Kylie has 832 songs on her portable media player. Lance has 3 times as many songs. how fewer songs can lance add to his player than Kylie can add to hers
A portable media can hold up to 9,000 songs. Therefore:
Kylie can add = 9000 – 832 = 8168
Lance can add = 9000 – 3 * 832 = 6504
So the difference is:
8168 – 6504 = 1664
Therefore lance can add 1664 fewer songs than kylie
