Which solid of revolution is produced by rotating the shape below 360° about the given axis?
Answers
Explanation:
When we rotate a rectangle around an axis of symmetry, we end up with a cylinder. Think of a revolving door or a turbine. The flat door moves through 3D space to produce or carve out a 3D cylinder.
This figure is composed of two rectangles, so we'll end up with two cylinders. They will both share the same center, so we'll have a sideways two-layer wedding cake structure when everything is said and done. This points to choice A as the final answer.
The solid of revolution, which is produced by rotating the shape below 360° about the provided axis, is the first one. Option A is correct.
What is solid of revolution?Solid of revolution is the method to obtain the solid figure by the plane. When a plane is revolving about an axis, a solid figure is obtained whose shape is depending on the shape of the plane.
In the problem,
A plane is given which is in the elbow shape. The axis around which it has to revolve is horizontal.The plane is kept at this axis from the base of it.The solid generated with this plane is full rotation, and it will look like the stand of the pole.
Thus, the solid of revolution, which is produced by rotating the shape below 360° about the provided axis, is the first one. Option A is correct.

Series:
Use the Arithmetic Series formula to calculate the sum:
-6+(-3)+0+ • • • + 162
(Hint: how many numbers are being added?)
Answers
Answer:
Step-by-step explanation:
The common difference is 3.
nth term = -6+(n-1)3
-6+(n-1)3 = 162
(n-1)3 = 168
n-1 = 56
n = 57
162 is the 57th term.
S₅₇ = 57×(a_1+a_{57})/2
= 57×(-6+162)/2
= 57×156/2
= 57×78
= 57×(-6+162)/2
= 4446

[tex]10\frac{1}{1}[/tex] km were covered on Thursday[tex]10\frac{1}{1}[/tex] km were covered on FridayOne is asked to find the total distance covered on both of these days. In order to do so, one must remember in a fraction, any number over (1) is equal to the numerator (number over the fraction bar). Thus one can form the following equation:
[tex](Thursday)+(Friday) = Total\ distance[/tex]
Substitute,
[tex](Thursday)+(Friday) = Total\ distance[/tex]
[tex](10\frac{1}{1})+(10\frac{1}{1}) = Total\ distance[/tex]
Simplify,
[tex](10\frac{1}{1})+(10\frac{1}{1}) = Total\ distance[/tex]
[tex](10+1)+(10+1) = Total\ distance[/tex]
[tex](11)+(11)=Total\ distance[/tex]
[tex]11+11=Total\ distance[/tex]

A baker made 6 pounds of dough. He used 8 9 of the dough to make sandwich rolls. How much of the dough is left over?
Answers
Answer:
2/3 pound of dough is left
Step-by-step explanation:
Amount of dough available = 6 pounds
The amount used in making sandwich rolls = 8/9 of the total amount
= [tex]\frac{8}{9} \times6 = 5\frac{1}{3} pounds[/tex]
Therefore, amount of dough left over [tex]= 6- 5\frac{1}{3} = \frac{2}{3} \\[/tex]
Hence, 2/3 pounds of dough is left
Working alone, it takes Scott 16 minutes to inflate twenty balloons, Ashley can inflate the same twenty balloons in 15 minutes. Find how long it would take them if they worked together.
Answers
Answer:
7.74 minutes
Step-by-step explanation:
Scott's rate = 20 /16 = 1.25
Ashley's rate = 20 / 15 = 1.333
Combined rate = (1.25 + 1.3333) = 2.583333
Hence, time it will take to inflate 20 balloons :
Rate = number of balloons / time taken
2.583333 = 20 / time taken
Time taken = 20 / 2.583333
Time taken = 7.7419
It will take them approximately 7.7 minutes to inflate 20 balloons

A prism is filled with 28 cubes with 1/2 unit lengths. What is the volume of the prism in cubic units?
Answers
Answer:
3.5 cubic units
Step-by-step explanation:
First, find the volume of one cube
Use the cube volume formula, V = s³, where s is the side length
V = (1/2)³
V = 1/8 cubic units
Now, find the volume of the prism by multiplying this by 28, since there are 28 cubes
28(1/8)
= 3.5
So, the volume of the prism is 3.5 cubic units
∠A and \angle B∠B are vertical angles. If m\angle A=(2x+26)^{\circ}∠A=(2x+26) ∘ and m\angle B=(3x+21)^{\circ}∠B=(3x+21) ∘ , then find the measure of \angle B∠B.
Answers
Answer:
36degrees
Step-by-step explanation:
If m<A and m<B are vertical angles, hence m<A = m<B (vertical angles are equal)
Given the following
m<A = (2x+26)°
m<B = (3x+21)°
Equating both expressions
2x + 26 = 3x + 21
2x - 3x = 21 - 26
-x = -5
x = 5
Get the measure of m<B
m<B = (3x+21)°
m<B = 3(5) + 21
m<B = 15+21
m<B = 36degrees
Hence the measure of angle B is 36degrees

[tex]8*a =b[/tex]
Required
Determine the true statement about b
The question is incomplete as options are not given. However, a general explanation is as follows:
Rewrite [tex]8*a =b[/tex]
[tex]b = 8 * a[/tex]
When a = 0
[tex]b = 8 * 0 = 0[/tex]
When a = 1
[tex]b = 8 * 1 = 8[/tex]
This means that:
For [tex]0 \le a \le 1[/tex]
Then [tex]0 \le b \le 8[/tex]
This means that: b is a number between 0 and 8

The lateral surface area of the given square pyramid is 80 cm².
What is lateral surface area?The lateral surface of an object is its entirety, excluding its base and top (when they exist).
Boundary - layer surface zone equals lateral surface area. This is to be contrasted from the total surface area, which includes the lateral surface area along with the base and top regions.
Given that, a square pyramid has side lengths each measuring 8 centimeters.
The height of the pyramid is 3 centimeters.
The lateral area of a square pyramid = 2al = 2a√[(a²/4) + h²]
= 2×8√[(8²/4) + 3²]
= 16√[(64/4) + 9]
= 16√[16 + 9]
= 16×5
= 80 cm²
Therefore, the lateral area of the pyramid is 80 cm².

7pi/theta = radius
Step-by-step explanation:
So we are using the arc length, central angle(in radians), and radius.
We know arc length, which is 7pi.
We don't know theta, which does not matter.
And finally, we don;t know radius, which is what we are looking for.
To find radius, we use:
arc length/theta=radius
Lets plug in our values:
7pi/theta=radius.
So the answer to the khan acadamy question is
7pi/∅
Here are some othr things that may help:
Radian * Radius = arc length
This solves for arc length
Here is another one:
