A cylinder and its dimensions are diameter 8.4 cm and height 10.9 cm. Which measurement is closest to the lateral surface area of the cylinder in square centimeters?​

Answer:

250 cm

Step-by-step explanation:

volume=length*width*height

v=10*5*5

v=250

Answer:

Yes, it is

Step-by-step explanation:

When the side lengths of a triangle are in the ratio 3: 4: 5, then it is a right triangle.

Answer:

Step-by-step explanation:

[tex] = 8 \frac{1}{4} \times 10 \frac{3}{4} [/tex]

[tex] = \frac{33}{4} \times \frac{43}{4} [/tex]

[tex] = \frac{1419}{4} [/tex]

[tex] = 354 \frac{3}{4} \: \: feet[/tex]

what is your question then?

8=x

Answer:

512 ft³

Step-by-step explanation:

The volume of a cube is (cube's side length)³, so this one would have a volume of 8³ = 512 ft³

Answer:

x=45

Step-by-step explanation:

A triangle adds up to 180º. The red lines in the bottom, left indicate that the triangle is a right triangle, meaning that one angle (the red angle) is 90º. When you subtract 180 by 90, you get 90. Then you divide that by 2, giving you 45.

Answer:

[tex]\frac{2-s}{4}=r[/tex]

Step-by-step explanation:

One solves a literal equation just like a normal algebraic expression with numbers, with inverse operations. Only that with a literal equation, there is a limit to how much one can simplify.

Inverse operations;

2 = 4r + s

-s         -s

2 - s = 4r

÷4       ÷4

[tex]\frac{2-s}{4}=r[/tex]

Given:

The surface area of a right circular cone is 32 sq. cm.

Scale factor for enlargement = 3

To find:

The surface area of the new cone.

Solution:

We know that enlargement of a shape forms a similar shape and area of the similar shapes is proportional to the square of their corresponding sides.

[tex]\dfrac{\text{Area of cone}}{\text{Area of new cone}}=\dfrac{\text{Radius of cone}^2}{\text{Radius of new cone}^2}[/tex]

Let the surface area of new cone be A and r be the radius of original cone

[tex]\dfrac{32}{A}=\dfrac{(r)^2}{(3r)^2}[/tex]

[tex]\dfrac{32}{A}=\dfrac{r^2}{9r^2}[/tex]

[tex]\dfrac{32}{A}=\dfrac{1}{9}[/tex]

By cross multiplication, we get

[tex]32\times 9=1\times A[/tex]

[tex]288=A[/tex]

The surface area of the new cone is 288 sq. cm.

Therefore, the correct option is C.

Answer:

A

Step-by-step explanation:

52º + 90º = 142º

142º - 180º = 38º

180º - 38º = 142º

Answer: This is the boundary line (aka bounding line)

Answer:

r = -33

Step-by-step explanation:

-r/3 = 11

Multiply each side by -3 to isolate r

-3 * -r/3 = 11 * -3

r = -33

Answer:

x=38

Step-by-step explanation:

Vertically opposite angles are equal, therefore equate the 2 angles opposite each other.

2x+5=3x-33

2x-3x= -33-5

-x= -38

x=38

Answer:

Because they are vertical angles:

(2x +5) = (3x-33)

combine like terms

5= x-33

x= 38

Step-by-step explanation:

hope this helps you

Answer: D

Step-by-step explanation:

-7 isn't greater than -4

Answer:

Step-by-step explanation:

Let the number of small boxes = x

and the number of large boxes = y

Total number of boxes = 24

Therefore, equation will be,

x + y = 24 ------ (1)

Since, volume of the smaller boxes = 9 cubic feet

And the volume of larger boxes = 24 cubic feet

Therefore, total volume of the boxes = (9x + 24y)

Since combined volume of all boxes = 441 cubic feet

Therefore, equation will be,

9x + 24y = 441 ------ (2)

Answer:

12.5%

Step-by-step explanation:

Total card = 52

Total number of red card = 26

So, Probability of first card is red = [tex]\frac{26}{52}[/tex] or [tex]\frac{1}{2}[/tex]

Total number of diamond card = 13

So, probability of second card is diamond =  [tex]\frac{13}{52}[/tex] or [tex]\frac{1}{4}[/tex]

So, probability that the first card is a red card and the second is a diamond can be calculated as follows,

Probability(first card, second card) = [tex]\frac{1}{2}[/tex] × [tex]\frac{1}{4}[/tex] = [tex]\frac{1}{8}[/tex] or 0.125

Probability(first card, second card) = 0.125 or 12.5%

Answer:

26 1/2

Step-by-step explanation:

convert 4 5/12 into 53/12

multiply 53/12 by 6 to get 53/2

turn 53/2 into a mixed number = 26 1/2

Answer:

26 1/2 (C)

Step-by-step explanation:

Turn the mixed number into a improper fraction and turn 6 into a improper fraction

6/1*53/12

Cross Multiply 6 can into 12 twice

1/1*53/2

Just Multiply

53/2

Turn into a Mixed Number

26 1/2
