volume is 100pi mm³.
What is volume?In mathematics, volume is the space taken by an object.
Here, given that,
The height of a cylinder is 4 millimeters.=h
The circumference of its base is 10 pi mm=2r*pi
So, we get,
r=5
Volume =pi*r²*h
=100pi mm³
Hence volume is 100pi mm³.

Solve this one following the linear equations beow agebricaly.Express your answer in simplest form.3(6x-4)=24
Answers
6x-4=8
Add 4 on both sides
6x=12
divide 12 by 6
Answer: x=2
Expand:
3(6x)=18x
3(-4)=-12
That gives, 18x-12=24
Subtract 12 from both sides to get 18x=12
x=12/18
Divide the numerator and the denominator by 6 to get:
x=2/3 which is the simplest form.

Answer:
[tex] \boxed{\sf None \: of \: the \: options \text{:} \: \: m =- \dfrac{13}{3}} [/tex]
Step-by-step explanation:
The slope m of a line passing through two points can be calculated using the following formula:
[tex] \sf m = \dfrac{rise}{run} = \dfrac{\Delta y}{\Delta x} = \dfrac{y_2 - y_1}{x_2 - x_1} [/tex]
[tex] \\ [/tex]
Let (x₁ , y₁) = (2 , -7)
Let (x₂ , y₂) = (-1 , 6)
Substitute these values into our formula:
[tex] \sf m =\dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{6 - (-7) }{-1 - 2 } = \dfrac{13}{-3}\\ \\ \implies \boxed{\sf m = -\dfrac{13}{3}} [/tex]

3. Which phrase best describes the function of the ATP molecule?
1. Carries energy
2. Destroy energy
3. absorbs energy
4. none of the above
Answers
Answer:
1.) Carries energy
Step-by-step explanation:
A good summary of an ATP molecule is a molecule that transfers energy between cells... meaning it carries energy from cell to cell. Furthermore, energy cannot be destroyed, and cannot be absorbed, only changed and transformed. This leaves us with two options, (1. Carries energy, and 4. None of the above). Since we already have a basic understanding of what an ATP molecule does, we can confidently determine that the correct answer is that an ATP molecule can best be described as carrying energy.

To indirectly measure the distance across a river, Nolan stands on one side of the river and uses sight-lines to a landmark on the opposite bank. Nolan draws the diagram below to show the lengths and angles that he measured. Find PRPR, the distance across the river. Round your answer to the nearest foot.
Answers
The length of PR to the nearest foot is 198.94 feet
Find the diagram attached
From the diagram, the triangle PRE and POC are similar triangles.
Let PR = x
Based on similarity theorem;
PR/RE = PR+RO/OC
x/135 = (x+140)/230
Cross multiply
230x = 135(x+ 140)
230x = 135x + 18,900
230x - 135x = 18,900
95x = 18900
x =18900/95
x = 198.94
Hence the length of PR to the nearest foot is 198.94 feet

Josiah skateboards from his house to school 3 miles away. It takes him 36 minutes.
How many minutes will it take Josiah to skateboard to his friend Sebastian’s house, which is 2 1/2
miles from school, if he travels at the same rate that he did from his house to school?
In the box below, type the number that goes in the blank.
Answers
Using the speed - distance relationship, the number of minutes it will take Josiah to cover a distance of 2.5 miles is 30 minutes.
Calculating Josiah's speed :
Speed = (distance ÷ time)Speed = (3 ÷ 36) = 0.08333 miles per minute.
Time taken to cover a distance of 2.5 miles :
Time taken = (Distance ÷ Speed)Time taken = (2.5 ÷ 0.08333) = 30 minutes
Therefore, it will take 30 minutes for Josiah to cover a distance of 2.5 Miles
