Step-by-step explanation:

Q9) Surface Area of a cylinder

= 2πr(r + h)

Diameter = 12cm , Radius = Diameter/2 = 12 cm/2

r = radius = 6cm

h = height = 10 cm

Surface area = 2 × π × 6(6 + 10)

= 603.18579 cm²

Approximately = 603.2 cm²

Q11) Volume of a rectangular prism

Length × Width × Height

Length = 6.5cm

Width = 8.5 cm

Height = 4 cm

Volume = 6.5 cm × 8.5 cm × 4 cm

Volume = 221 cm³

Q12) Volume of the cylinder = πr²h

r = radius = 1.7m

h = height = 9 m

Volume = π × 1.7 × 9

= 81.71 m³

Approximately = 81.7 m³

Q13) Volume of the cylinder = πr²h

Diameter = 0.8m, Radius = Diameter/2 = 0.8m/2

r = radius = 0.4m

h = height = 1.5 m

Volume = π × 0.4 × 1.5

= 0.75 m²

Approximately = 0.8 m³

Answer:

H.

Step-by-step explanation:

F is incorrect because you don't know how many service calls a person will make. G is incorrect for the same reason, but with texts. J is incorrect because 8 skirts per hour is making the graph unproportioned.

Answer:

Total bill will be BD 33.600

Step-by-step explanation:

28 multiplied by 20% = 5.6

Add 5.60 to the cost

28.00 + 5.60 = 33.600

hope this helps and is right. p.s. i really need brainliest :)

Step-by-step explanation:

Yes it is a function dearest

Answer:

Y = 10

Explanation:

We know that the left and top angles are 45°, the base is 10, and the bottom right angle is 90°, or a right angle. The simplest way I can explain this is the bottom side of the triangle is the same as the right side of the triangle. Meaning "y" would be 10 like the bottom.

If I'm right, I'd appreciate a brainliest as it'd really help me out :D

Answer:

3x² + 3x³ - x + 8

Step-by-step explanation:

All we have to do is add the terms together

(open parentheses as well)

3x² - 8x + 2 + 3x³ +7x +6

now, simplify

3x²+3x³-x+8

Answer:

V = 336 ft3

Step-by-step explanation:

1/2*7*16*6

336

Answer: 336 ft cubed

Step-by-step explanation:

Formula is 1/2 times B times L times H so, 7 times 6 is 42, 42 times 16 is 672 and 672 divided by 2 or multiplied by 1/2 is 336

Answer:

2/3

Step-by-step explanation:

Total marbles:

4 + 3 + 2 = 9

Non-white marbles:

4 + 2 = 6

Probability of not drawing a white marble:

6/9

2/3

Answer:

6/9

Step-by-step explanation:

n=numerator

d=denominator

b=blue

p=pink

w=white

m=marbles

What we know:

4 bm

2pm

3 wm

what we need to know:

we need to know the denominator (all the numbers added up) and the numerator (the marbles that aren't white marbles).

work:

n= 4+2=6

d= 4+3+2=9

so it is 6/9

Answer:

The probability that I pick a magic elf is 6.66%.

Step-by-step explanation:

Since there are 3 characters (elf, hobbit, or human) and 5 defense tools (magic, sword, shield, slingshot, or umbrella) to pick from, if I randomly choose my character and tool, to determine what is the probability that I'll be a magic elf, the following calculation must be performed:

1/3 x 1/5 = X

0.3333 x 0.2 = X

0.0666 = X

0.0666 = 6.66%

Therefore, the probability that I pick a magic elf is 6.66%.

Answer:

a=8

Step-by-step explanation:

2a+8=16

-8 on both sides

2a=8

/2 on both sides

a=4

Answer:

(i)

Given

Also we see that

Since two angles of triangles are congruent, the triangles are similar by AA similarity postulate

(ii)

In similar figures corresponding parts have same ratio. Use ratios to find the value of x:

Answer:

=28x

Correct choice is J

Answer:

Step-by-step explanation:

[tex]\frac{7+5x+4+8+6}{5} = 10[/tex]

7+5x+18=50

5x+25 = 50

5x = 25

x = 5

Answer:

5

Answer:

18.76%

Step-by-step explanation:

effective interest rate = ( 1 + periodic interest rate)^m - 1

m = number of compounding = 365

Periodic interest rate = APR / number of compounding = 17.2 / 365 = 0.0471% = 0.000471

(1 + 0.000471) ^365 - 1 = 18.76%

Answer:

[tex]V=209\ cm^3[/tex]

Step-by-step explanation:

The height of this cone, h = 8 cm

The radius of this cone, r = 5 cm

We need to find the volume of this cone. The formula for the volume of a cone is given by :

[tex]V=\dfrac{1}{3}\pi r^2 h[/tex]

Put all the values,

[tex]V=\dfrac{1}{3}\times 3.14\times 5^2 \times 8\\\\=209.33\approx 209\ cm^3[/tex]

So, the volume of this cone is equal to [tex]209\ cm^3[/tex].
