Find the volume of the cone.
12 cm
r = 8 cm
V = [?] cm3
Round to the nearest tenth.
Enter
Answer:
V = 803.8 cm^3
Step-by-step explanation:
h = 12cm
r = 8cm
V = [tex]\frac{1}{3}[/tex] [tex]\pi[/tex][tex]r^{2}[/tex]h
V = [tex]\frac{1}{3}[/tex] [tex]\pi[/tex][tex](8)^{2}[/tex] (12)
V = 4 [tex]\pi[/tex] (64)
V = 803.84
Answer:
800
Step-by-step explanation:
[tex]V=\pi r^{2} \frac{h}{3}[/tex]
[tex]V=\pi 8^{2} \frac{12}{3} \\V=\pi (64)(4) = 256\pi[/tex]
256π = 804.247719319
To the nearest tenth: 800
Convert 3 qt/min to gallons per hour.
45 gal/h
12 gal/h
180 gal/h
4.5 gal/h
Given:
3 qt/min
To find:
The conversion of 3 qt/min to gallons per hour.
Solution:
We know that,
1 quart = 0.25 gallons
60 minutes = 1 hour
1 minute = [tex]\dfrac{1}{60}[/tex] hour
Using these conversions, we get
[tex]3 \dfrac{qt}{min}=\dfrac{3\times 0.25}{\dfrac{1}{60}}\ \dfrac{gal}{h}[/tex]
[tex]3 \dfrac{qt}{min}=3\times 60\times 0.25\ \dfrac{gal}{h}[/tex]
[tex]3\ qt/min=45\ gal/h[/tex]
Therefore, the correct option is A.

Step-by-step explanation:
In 1846 the depth of the river was 6.7 feet deep. In 1847 it dropped 9%. This year, 1848, it rose 7% What is the depth now.
Answer:
6.5237 feet.
Step-by-step explanation:
initial depth of river H = 6.7 ft
In 1847 it dropped 9%, this means the new depth will be 91% of 6.7
that is (91/100)×6.7 = 6.097 ft
Now in the year , 1848 the depth gain rose by 7%, this means now the new depth 107% of 6.097
= (107/100)×6.097 = 6.5237 feet.
Therefore, new of the depth of river in 1848 = 6.537 ft
The measures of interior angle of a convex pentagon are in ratio 1:2:3:4:5. Find the measures of each angle
Answer:
The angles have measurements 36, 72, 108, 144, and 180.
Step-by-step explanation:
Pentagon has 5 sides and 5 angles.
The amount of triangles formed by choosing one vertex and drawing from that vertex to every nonadjacent vertex is 3.
3(180)=540 which is the sum of the angles in a pentagon.
So since the ratio is 1:2:3:4:5, that means the angles are 1x,2x,3x,4x, and 5x.
We have the equation 1x+2x+3x+4x+5x=540 to solve.
15x=540
Divide 15 on both sides:
x=540/15
x=36
1x=36
2x=72
3x=108
4x=144
5x=180
The angles have measurements 36, 72, 108, 144, and 180.
What is the weight of a 22 kg object on the surface of the moon (g = 1.6 m/s2)?
Weight is the gravitational force by which a massive object attracts on another object .
So,
f = m × g
where,
f = force / weight m = mass ( 22 kg )g = acc due to gravity ( 1.6 m/s² )=》
[tex]f = 22 \times 1.6[/tex]

In the diagram shown overline AD and intersect at point E. overline AB and overline CD are parallel . Given the segment length shown in the picture, which of the following is the length overline AE
1) 11.25
2) 10.8
3) 10
4) 7.5
Answer:
11.25
Step-by-step explanation:
Since AB and CD are parallel, ∠D is congruent to ∠A and ∠C is congruent to ∠B. Therefore the two triangles are similar by the AA postulate. Now, the corresponding sides are in proportion
Since AE ↔ DE and AB ↔ CD
So, AE/CD = AB/CD
AE/5 = 9/4
AE = 9(5)/4
= 45/4 = 11.25
What is the intermediate step in the form (x + a)2 = b as a result of completing the
square for the following equation?
X2 + 23x – 19 = 9x - 4
Answer:
(x + 7)^2 = 64
Step-by-step explanation:
x^2 + 23x – 19 = 9x - 4
x^2 + 23x - 9x = -4 + 19
x^2 + 14x = 15 = 0
Completing the square:
(x + 14/2)^2 - (14/2)^2 = 15
(x + 7)^2 - 49 = 15
(x + 7)^2 = 64

Answer:
2) y = 0.5^x
Step-by-step explanation:
Plug in x coordinates to see which equation makes up the graph. We can see that the y values lower even after using positive numbers so this eliminates the possibility of 1) as that would make the y values increase. Starting with coordinates (-1, 2), let's plug these into 2):
y = 0.5^x
2 = 0.5^-1
2 = 2
Correct
Use another pair of coordinates to see if it still works:
(-2, 4)
4 = 0.5^-2
4 = 4
It does!
Check the other equations just to make sure this is the only option:
2 = 5^(- - 1)
Negative + Negative = Positive
2 = 5^1
2 = 5
Incorrect.
2 = 0.5^(- - 1)
2 = 0.5^1
2 = 0.5
Incorrect.
This means our first solution is the only solution.

Miss Torres is mailing a package that way it's 12.5 pounds the post office charges by the ounce to mail a package how much does the package weight in ounces
Answer: 200 ounces
Step-by-step explanation:
One pound is the equivalent of 16 ounces.
To convert 12.5 pounds to ounces therefore, one needs to multiply 12.5 by 16 ounces:
= 12.5 * 16
= 200 ounces
The package to be mailed weighs 200 ounces when converted from pounds.
Answer:
200 ounces
Step-by-step explanation:
we need to convert 12.5 pounds to ounces
1 pound = 16 ounces
16 x 12.5 = 200 ounces

From the figure, we can notice that : Surface area of the pyramid is equal to Sum of the area of the square and Sum of the areas of 4 triangles.
We know that : Area of a square is given by : Side x Side
Given : Side of the square = 3 cm
⇒ Area of the square = 3 x 3 = 9 cm²
We know that : Area of the triangle = 1/2 x Base x Height
From the figure, We can notice that, Base of each triangle = 3 cm and height of the each triangle = 3 cm
⇒ Area of one triangle = 1/2 × 3 × 3 = 4.5 cm²
Surface area of the pyramid = Surface of the square + Surface area of the 4 triangles
⇒ Surface area of the pyramid = 9 cm² + 4(4.5) cm²
⇒ Surface area of the pyramid = 9 cm² + 18 cm² = 27 cm²
Answer : Surface area of the pyramid = 27 cm²
