Answer:
V = 54π or V = 169.56 units³
Step-by-step explanation:
The volume of a cylinder is given by the formula:
V = πr²h
If we use 3.14 as pi we get this:
V = (3.14)×(3)²×(6)
V = 3.14×9×6
V = 3.14×54
V = 169.56
Since it is volume the units will be units³
So our final answer is 169.56 units³
If you wanted an exact in pi form you would do the same steps but not simplify pi:
V = πr²h
V = π×(3)²×6
V = π×9×6
V = 54π
Allie identifies the coordinates of point D as (3, 7). Explain her error and explain how to correctly identify the ordered pair. hurry
Here Allie mistook the x and y axis completely oppositely.
→ First should be the x axis and then the y axis, (x, y)
Answer:
Step-by-step explanation:
Coordinates of a point are usually represented by (x, y) where x describes the horizontal distance from the y-axis and y describes the vertical distance from the x-axis.
Point A
4 units from the y-axis ⇒ x = 4
6 units from the x-axis ⇒ y = 6
A = (4, 6)
Point B
2 units from the y-axis ⇒ x = 2
9 units from the x-axis ⇒ y = 9
B = (2, 9)
Point C
0 units from the y-axis ⇒ x = 0
4 units from the x-axis ⇒ y = 4
C = (0, 4)
Point D
Allie has mixed up the x and y coordinates of D.
7 units from the y-axis ⇒ x = 7
3 units from the x-axis ⇒ y = 3
D = (7, 3)

Answer: 176 cubic cm
Step-by-step explanation:
Formula for finding volume is l x w x h
The first rectangle on the bottom:
2 x 2 x 8 = 32
The second rectangle next to it:
3 x 6 x 8 = 144
Now add the two values to get the volume of the figure
144 + 32= 176
Tell whether the ratios form a proportion. 14:8 and 28:10
Answer:
no

What is the magnitude and direction of RS with tail and head points R(4, -6) and S(-2, 1)?
9.2 units, 49.4° north of west
10.4 units, 40.6° north of west
9.2 units, 49.4° south of east
10.4 units, 40.6° south of east
Using vector concepts, it is found that the correct option regarding the magnitude and the tail is given by:
9.2 units, 49.4° north of west
How do we find the vector, and what is it's magnitude?To find them, we subtract the end coordinate by the start coordinate, hence:
RS = S - R = (-2, 1) - (4,-6) = (-6,7).
The magnitude is given by the square root of the sum of the squares of each coordinate, hence:
[tex]|RS| = \sqrt{(-6)^2 + 7^2} = \sqrt{85} = 9.2[/tex]
Considering a xy graph, the vector is decaying, that is, moving north of west, hence the correct option is:
9.2 units, 49.4° north of west

A cylindrical specimen of cold-worked copper has a ductility (%el) of 25%. if its cold-worked radius is 10 mm, what was its radius (in mm) before deformation
The radius of the copper specimen before deformation was 8 mm of a cylindrical specimen of cold-worked copper has a ductility (%el) of 25%. if its cold-worked radius is 10 mm
Given information:
Ductility (%el) of cold-worked copper = 25%Cold-worked radius = 10 mmTo find the radius of the copper specimen before deformation, we'll use the formula for calculating the ductility:
Ductility (%el) = ((Final radius - Initial radius) / Initial radius) * 100
Let's denote the initial radius as "r" (in mm). The final radius is 10 mm (after cold-working).
25% = ((10 - r) / r) * 100
Now, solve for "r":
25% = (10 - r) / r
Convert percentage into fraction:
25/100 = (10 - r) / r
Convert fraction into decimal:
0.25 = 10 - r/r
on Cross-multiplication gives:
0.25r = 10 - r
Add r on both sides gives,
1.25r = 10
On dividing by 1.25 gives:
r = 8 mm
So, the radius of the copper specimen before deformation was 9.75 mm.

This are 3 triangles
One big one, that is divided into 2
Of the 2 triangles one is smaller than the other
So
inside the big trangle we have:
Small triange (Small side = 8/ Median side = y /large side =12
Median triangle(small side = y/ Median side = x/ Large side = z
And then the 2 triangles make a big triangle:
Large triangle (small side=12/ Median side= z/ Large side = 8+x
If f(x) is a linear function such that f(2)= 5 and f(4) = 13, f(x) = ?
A) 3x - 4
B) 4x - 3
C) 4x + 3
D) 1/4x + 9/2
Answer: you are on your own.
Step-by-step explanation:
The equation of the linear function f(x) is f(x) = 4x - 3. So, the answer is B) 4x - 3.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
We can use the two given data points to determine the equation of the linear function f(x) using the slope-intercept form:
f(x) = mx + b
where m is the slope and b is the y-intercept.
First, we can find the slope of the function by using the formula:
m = (y₂ - y₁) / (x₂ - x₁)
where (x₁, y₁) = (2, 5) and (x₂, y₂) = (4, 13)
m = (13 - 5) / (4 - 2) = 4
Now we can use the slope and one of the given points to solve for the y-intercept:
5 = 4(2) + b
b = -3
Therefore, the equation of the linear function f(x) is f(x) = 4x - 3.
