A cylinder has a volume of 78cm3 What is the volume of a cone with the same radius and height?
Answers
Answer:Volume of cylinder V= bh= 78 cm^3,
where b is area of base(circle). Then volume of cone = 1/3bh =1/3*78 = 26 cm^3Upvote•0Downvote Add comment
Answer :D
The volume of the cone is [tex]26^{}[/tex] [tex]cm^{3}[/tex]
Question explanation:
Okay, so, we know that.
The volume of a cylinder is equal to:
[tex]V^{}[/tex] [tex]=[/tex] [tex]\pi[/tex][tex]r^{2}[/tex][tex]h[/tex]
In this problem, we have that:
[tex]V[/tex] [tex]=[/tex] [tex]78[/tex] [tex]cm^{3}[/tex]
So:
[tex]78 =[/tex] [tex]\pi[/tex][tex]r^{2}[/tex] [tex]h[/tex] [tex]=[/tex] [tex]equation[/tex] [tex]A[/tex]
The volume of a cone with the same radius and height is equal to
[tex]V =[/tex] [tex]\frac{1}{3}[/tex] [tex](\pi r^{2} h)[/tex] [tex]= equation[/tex] [tex]B[/tex]
Substitute equation A in equation B
[tex]V = \frac{1}{3} (78)[/tex]
[tex]V = 26^{}[/tex] [tex]cm^{3}[/tex]

Answer:
1/(x -2)
Step-by-step explanation:
You want the simplified form of the rational expression ...
[tex]\dfrac{1}{x-4}-\dfrac{2}{x^2-6x+8}[/tex]
SimplificationWe simplify this by combining terms over a common denominator, then cancelling any common factors from numerator and denominator.
[tex]\dfrac{1}{x-4}-\dfrac{2}{x^2-6x+8} = \dfrac{(x-2)}{(x-4)(x-2)}-\dfrac{2}{(x-4)(x-2)}\\\\\\=\dfrac{(x-2)-2}{(x-4)(x-2)}=\dfrac{x-4}{(x-4)(x-2)}=\boxed{\dfrac{1}{x-2}}[/tex]
Note that the domain still excludes x=4, in addition to the obvious exclusion of x=2.

Which is the best statement of the angle-angle similarity theorem?
A. When the preimage of a triangle is a dilation of the image, the triangles are similar.
When triangles have two pairs of corresponding angles that are congruent, the third pair of angles is also congruent.
B. When triangles have two pairs of corresponding angles that are congruent, those triangles are similar.
C. When the interior angles of a polygon sum to 180 degrees that polygon is a triangle.
Answers
The best statement of the angle-angle similarity theorem is (a) When the preimage of a triangle is a dilation of the image, the triangles are similar.
How to determine the similarity statement?The angle-angle similarity theorem is used in similar triangles; especially when a triangle is dilated (i.e. resized) to form another triangle
When triangles are dilated, the corresponding angles in both triangles (i.e. the image and the pre-image) are always equal
Hence, the best statement of the angle-angle similarity theorem is (a)

The process is fundamentally identical to finding the difference of numerical fractions. The least common denominator is found by considering factors of the denominators, just as it would be if they were pure numbers.

he tables show the numbers of white and yellow flowers Cara and Hector used in 5 different arrangements.
Cara’s Flower Arrangements
White 3 6 9 12 15
Yellow 5 10 15 20 25
Hector’s Flower Arrangements
White 4 8 12 16 20
Yellow 6 10 14 18 22
Part A
Are the numbers of white and yellow flowers in Cara’s arrangements proportional?
Which equation relates the number of white flowers, w, to the number of yellow flowers, y?
Yes; y=35w
Yes; y=53w
No; y=3w+5w
No; y=5+3w
Part B
Are the numbers of white and yellow flowers in Hector’s arrangements proportional?
Which equation relates the number of white flowers, h, to the number of yellow flowers, e?
Yes; e=32h
Yes; e=23h
No; e=h+2
No; e=h−2
Answers
Answer:
A.
1. no, y = 5 + 3w
B.
no, e = h + 2
Step-by-step explanation:
Using the principle of proportional relationship to model the two tables, we can infer that, the first first table is proportional while the second isn't.
Clara's arrangement :
White (w)Yellow (y)Testing if relationship is proportional :
y = kw5 = 3k
[tex] k = \frac{5}{3}[/tex]
Yes, the relationship is proportional [tex] y = \frac{5}{3}w[/tex]
Hector's arrangement :
White (h)Yellow (e)The number of yellow flowers surpasses the number of white flowers by a constant value of 2.
Hence, the relationship can be modeled thus ;
e = h + 2Therefore, the relationship is not proportional.
