Answer:
The first step is to find the volume of the two hemispheres.
Step-by-step explanation:
[tex]\boxed{volume \: of \: sphere = \frac{4}{3} \pi {r}^{3} }[/tex]
Since the 2 hemispheres have the same radius, we can simply find the volume of a sphere.
Volume of sphere
[tex] = \frac{4}{3}( \pi)( {12}^{3} )[/tex]
[tex] = 2304\pi \: in^{3} [/tex]
Volume of solid
= volume of cylinder -volume of 2 hemispheres
Let's find the volume of the cylinder.
[tex]\boxed{voume \: of \: cylinder = \pi {r}^{2}h }[/tex]
Volume of cylinder
[tex] = \pi( {12}^{2} )(24)[/tex]
[tex] = 3456\pi \: in^{3} [/tex]
Thus, volume of solid
[tex] = 3456\pi - 2304\pi[/tex]
[tex] = 1152\pi[/tex]
[tex] = 1152(3.14)[/tex]
[tex] = 3617.28 \: in^{3} [/tex]
Answer:
Solution :-Volume of solid = Volume of Sphere - Volume of cylinder
Volume = 4/3πr³ - πr²h
Volume = 4/3 • π • 12³ - π • 12² • 24
Volume = 4/3 • π • 1728 - π • 144 • 24
Volume = 4 • π • 576 - π • 3456
Volume = π(3456 - 2304)
Volume = π(1152)
Volume = 3619.11 in³

Find the area of the regular hexagon round answer to the nearest tenth.
Answer:
280.6 [tex]m^2[/tex]
Step-by-step explanation:
find the length of each side:
you're only given h = 9 m
the formula for h is [tex]h=\frac{\sqrt{3} }{2} *a[/tex], where a is a side length of the hexagon
plug h in:
[tex]9=\frac{\sqrt{3}}{2}*a\\\\a=9*\frac{2}{\sqrt{3}}\\\\[/tex]
a ≈ 10.392 m
now find the area of a triangle:
1/2 (10.392)(9) = 46.764 [tex]m^2[/tex]
multiply that by 6 and you get 280.584 ≈ 280.6 [tex]m^2[/tex]
you can also use the regular hexagon area formula instead of finding the individual area and multiplying by 6: [tex]\frac{3\sqrt{3} }{2} *a^2[/tex]

Step-by-step explanation:
3. Colin found apples on sale for 6 for $2.18. He wanted
to make some apples cider, and bought 4 dozen apples.
How much did he pay?
Answer: $17.44
Step-by-step explanation:
4 (dozens) ×12 (total number in a dozen) = 48 (total apples)
48÷6= 8. This was divided so there is equal groups of 6.
8 (number of groups of six) x 2.18 (cost of 6 apples)= 17.44
$17.44 was the total cost.

What is the area of this triangle?
Answer:
The area of this triangle is.. [tex]30 in^2[/tex]
Step-by-step explanation:
6 x 10 divided by 2 = 30
Answer:
30 cm²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 6 and h = 10 , then
A = [tex]\frac{1}{2}[/tex] × 6 × 10 = 3 × 10 = 30 cm²

119.48×20.4=. 2437.392
Colorado Springs sales tax is 8%. If you bought a sweatshirt for $20
(Remember money always has two decimal places: $0.00)
the amount of sales tax would be: $
the total purchase amount would be: $
Answer:
the amount of sales tax and the total purchase amount is $1.60 and $21.60 respectively
Step-by-step explanation:
Given that
The sales tax rate is 8%
And, the purchase price of sweatshirt is $20
We need to find out the sales tax and the total purchase amount
The sales tax is
= $20 × 8%
= $1.60
And, the total purchase amount is
= $20 + $1.60
= $21.60
Hence, the amount of sales tax and the total purchase amount is $1.60 and $21.60 respectively

Answer:
12.56
Step-by-step explanation:
d = 2r = 2(2 m) = 4 m
C = πd = 3.14 × 4 m = 12.56 m
Answer:
C=12.56 m
Step-by-step explanation:
The radius is 2 m. To find the circumference, you need d, which is the diameter.
The diameter of a circle is 2 times the radius.
d=2*2=4
Now use the formula to find the circumference
C=3.14*4=12.56
What would the answer to this question be?
A. 40°
B. 60°
C. 80°
D. 100°
Answer:
D. 100°
Step-by-step explanation:
A straight line is 180°. Add 50° and 30° (which is 80°) and subtract the total from 180°.
50 + 30 = 80
180 - 80 = 100
Answer:
These angles form a straight line, so they are supplementary angles.
We know that, supplementary angles form 180°.
[tex]50 + x + 30 = 180 \\ 50 + 30 + x = 180 \\ 80 + x = 180 \\ x = 180 - 80 \\ x = 100[/tex]
=> So, the missing angles is 100°

Find the distance between the two points rounding to the nearest tenth (if necessary).
(6,-6) and (2,-2)
Answer:
The answer is 5.7
Step-by-step explanation:
To find the answer you would use the distance formula
[tex]\sqrt({x}_{2} -{x}_{1 )^{2} + (Y_{2} - Y_{1})^{2}[/tex]
The square root of X2 minus X1 plus Y2 minus Y1
You are given 2 points which means that you have your Xs and Ys needed.
We will use (6,-6) as our X and Y 1
We will use (2,-2) as our X and Y 2
Now all you do is plug in the numbers
[tex]\sqrt{2-(6)} + \sqrt{-2-(-6)}[/tex] Square them both
Simplify
[tex]\sqrt{-4} ^2+\sqrt{-4}^2[/tex]
Simplify again
-4 *-4 =16
4*4= 16
16+16= 32
Your answer is[tex]\sqrt{32}[/tex]
Or simplified 5.656
