A lampshade has a height of 12cm and upper and lower diameters of 10cm and 20cm A)what area of material is required to cover that curved surface of the frustum B)what is the volume of the frustum (Give both answers in terms of pie)
Answer:
[tex](a)\ Area = 195\pi[/tex]
[tex](b)\ Volume = 700\pi[/tex]
Step-by-step explanation:
Given
[tex]h = 12[/tex]
[tex]d_1 = 10[/tex] --- lower diameter
[tex]d_2 = 20[/tex] --- upper diameter
Solving (a): The curved surface area
This is calculated as:
[tex]Area = \pi l(r_1 + r_2)[/tex]
Where
[tex]r_1 = 0.5 * d_1 = 0.5 * 10 = 5[/tex] --- lower radius
[tex]r_2 = 0.5 * d_2 = 0.5 * 20 = 10[/tex] --- upper radius
And
[tex]l = \sqrt{h^2 + (r_1 - r_2)^2[/tex] ---- l represents the slant height of the frustrum
[tex]l = \sqrt{12^2 + (5 - 10)^2[/tex]
[tex]l = \sqrt{12^2 + (-5)^2[/tex]
[tex]l = \sqrt{144 + 25[/tex]
[tex]l = \sqrt{169[/tex]
[tex]l = 13[/tex]
So, we have:
[tex]Area = \pi l(r_1 + r_2)[/tex]
[tex]Area = \pi * 13(5 + 10)[/tex]
[tex]Area = \pi * 13(15)[/tex]
[tex]Area = 195\pi[/tex]
Solving (b): The volume
This is calculated as:
[tex]Volume = \frac{1}{3}\pi * h * (r_1^2 + r_2^2 + (r_1 * r_2))[/tex]
This gives:
[tex]Volume = \frac{1}{3}\pi * 12 * (5^2 + 10^2 + (5 * 10))[/tex]
[tex]Volume = \frac{1}{3}\pi * 12 * (25 + 100 + (50))[/tex]
[tex]Volume = \frac{1}{3}\pi * 12 * (175)[/tex]
[tex]Volume = \pi *4 * 175[/tex]
[tex]Volume = 700\pi[/tex]

Answer:
x = 1+sqrt(69)/8 about 2.0383
or
x = 1-sqrt(69)/8 about -0.0383
Step-by-step explanation:
Use the quadratic formula:
(Move 17 to the left side first though)
(-b±√(b²-4ac))/2a
(1±sqrt(1-4*1*-17))/2(4)
x = 1±sqrt(69)/8
The most efficient method is the quadratic equation because the equation is not easily factorable and a!=1.

Step-by-step explanation:
i took the test
The volume of prism for the given condition is 147 cm³.
What is volume of prism?A prism is a polyhedron comprising an n-sided polygon base, a second base which is a translated copy of the first, and n other faces, necessarily all parallelograms, joining corresponding sides of the two bases.
Here, Prism(Rectangle)
Length(L) = 3.5 cm.
Width(W) = 6 cm
Height (H) = 7 cm
Volume = Area of Rectangle x Height
Volume of Prism: V = L x W x H
V = 3.5 X 6 X 7
V = 147 cm³
Thus, The volume of prism for the given condition is 147 cm³.

in a school ,the number of boys who play cricket is 3 times as much as a number of boys who play tennis. if 12 boys, who play cricket, play tennis instead, the number of boys who play each of these sports would be the same. find the number of boys who play tennis
Answer:
The number of boys who play tennis is 36.
Step-by-step explanation:
Let the number of boys who play tennis is x.
number of boys who play cricket = y
x = 3 y..... (1)
12 boys plays both cricket and tennis.
According to the question,
x - 12 = y + 1 2
3 y - 12 = y + 12
2 y = 24
y = 12
So, the number of boys who plays tennis is x = 3 x 12 = 36.

if P =(-1,6),find Rx-axis (P
Answer:
-1,-6
Step-by-step explanation:
The reflection of point P=(-1,6) across the x-axis is the point (-1,-6).
What is reflection?In mathematics, reflection is a transformation that flips a shape, point, or object over a line, plane, or point. Reflection is also known as flipping, mirroring, or symmetry.
In two-dimensional geometry, the most common type of reflection is a mirror reflection, which involves flipping a shape or point over a line (known as the line of reflection) to create a mirror image. The line of reflection acts as a mirror, and the shape or point is reflected in the mirror as if it were a real reflection.
To find the reflection of the point P=(-1,6) across the x-axis, we can use the following formula:
Rx-axis(P) = (x, -y)
where x is the x-coordinate of P, and y is the y-coordinate of P.
In this case, the x-coordinate of P is -1, and the y-coordinate of P is 6. Therefore, the reflection of P across the x-axis, Rx-axis(P), is:
Rx-axis(P) = (-1, -6)
So the reflection of point P=(-1,6) across the x-axis is the point (-1,-6).

Answer:
-5
Step-by-step explanation:
When rotating a point (x,y) 270 degrees counterclockwise, the new coordinates become (y, -x).
Answer:
(4, -5)
Step-by-step explanation:
Seeing as the coordinates of P are (5, 4) and it's a 270 degrees rotation, the transformation rule is:
[tex](x,y)[/tex] turns into [tex](y, -x)[/tex].
Thus, (5, 4) turns into (4, -5)

True or False: △XYZ has sides XY, YZ and XZ that measure 15 cm, 20 cm, and 25 cm respectively is a right triangle.
Please answer please
Answer:
True
Step-by-step explanation:
As a right triangle, it follows the Pathagorem Therom. All you have to do is multiply 15 x 15 = 225 and 20 x 20 = 400, then finally, you would do 25 x 25, which is the biggest number of all, and get 625. Since 225 + 400 = 625, this follows the Pathagorem Therom.

Two similar cylinders have radii of 15 inches and 6 inches. What is the ratio of the surface area of the small cylinder to the surface area of the large cylinder.
Answer:
4:25
Step-by-step explanation:
Given that,
r₁ = 15 inches, r₂ = 6 inches
The area of the cylinder is given by :
[tex]A=2\pi rh+2\pi r^2[/tex]
The ratio of surface areas of two cylinders,
[tex]\dfrac{S_2}{S_1}=\dfrac{2\pi r_2h_2+2\pi r_2^2}{2\pi r_1h_1+2\pi r_1^2}\\\\\dfrac{S_2}{S_1}=(\dfrac{r_2}{r_1})^2\\\\=\dfrac{6}{15}^2\\\\=\dfrac{4}{25}[/tex]
Hence, the required ratio is 4:25.

help me plz i’m begging :(
Answer:
(x2 +2x+1)+(y2+4y)=31+1
(x+1)2 +(y2+4y)=32
(x+1)2 +(y2+4y+4)=32+4
(x+1)2 +(y+2)2=36
The equation can be written in the form (x-p)2 +(y-q)2=r2
so it represents a circle with the radius r=6 and the center (-1,-2)
