Volume of a cone = \pi r^2\frac{h}{3}

Volume of a sphere = \frac{4}{3} \pi r^3

Volume of a cylinder = \pi r^2h

With the help of these formulas, we can calculate the volumes.

A cone with a radius of 12 units and a height of 6 units = \pi 12^2\frac{6}{3} = 288\pi

A sphere with a diameter of 12 units = \frac{4}{3} \pi 6^3 = 288\pi

A sphere with a radius of 9 units = \frac{4}{3} \pi 9^3 = 972\pi

A cylinder with a diameter of 12 units and a height of 27 units = \pi 6^227 = 972\pi

A cylinder with a diameter of 8 units and a height of 18 units = \pi 4^218 = 288\pi

A cone with a diameter of 18 units and a height of 36 units = \pi 9^2\frac{36}{3} = 972\pi

<u>QUESTION 1</u>

The volume of a cone is given by;

V=\frac{\pi r^2h}{3}


From the given information,

r=12,h=6


V=\frac{12^2\times 6}{3}\pi


V=\frac{144 \times 6}{3}\pi


V=288\pi


<u>QUESTION 2</u>


The volume of a sphere is given by

V=\frac{4\pi r^3}{3}


From the given information.\

r=\frac{Diameter}{2}= \frac{12}{2}=6



Therefore the volume of the sphere is


V=\frac{4\times6^3}{3} \pi


V=\frac{4\times216}{3} \pi


V=288\pi



<u>QUESTION 3</u>


The volume of a sphere is given by

V=\frac{4\pi r^3}{3}


From the given information.\

r=9



Therefore the volume of the sphere is


V=\frac{4\times 9^3}{3} \pi


V=\frac{4\times 729}{3} \pi


V=972\pi


<u>QUESTION 4</u>

The volume of a cylinder is given by


V=\pi r^2 h


From the given information,

r=\frac{Diameter}{2}= \frac{12}{2}=6


and

h=27


Therefore volume of the cylinder


V=6^2 \times 27 \pi


V=36 \times 27 \pi


V=972\pi


<u>QUESTION 5</u>


The volume of a cylinder is given by


V=\pi r^2 h


From the given information,

r=\frac{Diameter}{2}= \frac{8}{2}=4


and

h=18


Therefore volume of the cylinder


V=4^2 \times 18 \pi


V=16 \times 18 \pi


V=288\pi






<u>QUESTION 6</u>


The volume of a cone is given by;

V=\frac{\pi r^2h}{3}


From the given information,

r=\frac{18}{2}=9,h=36


V=\frac{9^2\times 36}{3}\pi


V=\frac{81 \times 36}{3}\pi


V=972\pi

Write the slope-intercept form of the equation of the line described.
Svetach [21]

Answer:

1) y = 2/3x - 2

2) y = -1/2x + 3

Step-by-step explanation:

1) Parallel lines have the same slopes. Write it in standard form (y = mx + c), then substitute the values of the coordinates into the equation.

y = 2/3x + c

0 = 2/3(3) + c

0 = 2 + c

0 - 2 = c

- 2 = c

Therefore, the slope-intercept form for the first part is y = 2/3x - 2.

2) Parallel lines have the same slopes. Write it in standard form (y = mx + c), then substitute the values of the coordinates into the equation.

y = -1/2x + c

1 = -1/2(4) + c

1 = -2 + c

1 + 2 = c

3 = c

Therefore, the slope-intercept form for the second part is y = -1/2x + 3.

The spinner below is spun, then a month of the year is randomly selected. Find the probability of P(unshaded, then a month that
lana [24]

Answer:

C)150

Step-by-step explanation:

P (blue)  fraction = 2/8   decimal=.25     percent=25%

P(purple) fraction=0/8   decimal=0         percent =0%

P(not green)  fraction=5/8     decimal=.625     percent= 62.5%

P(not brown) fraction=8/8     decimal=1   percent =100%

2)Refer to the table on air travel selected airports. Suppose a flight that arrived at El Centro is selected at random. What is the probability that the flight did not arrive on time? write your answer as a fraction, decimal and percent.    

80% on time so 20% are not on time

20/100 ÷ 20 =1/5

20%, .2, 1/5

3)The spinner has 8 sectors labeled with letters. Each sector of the spinner below is the same size, as shown.

If the arrow is spun 400 times , how many times  would it be  expected to land on a sector labeled B?

A)50                 C)150

B)100                D)250

Need help what is this
Ann [662]

Answer:

2nd option

Step-by-step explanation:

Substitute the values of x from the domain into f(x) for range

f(2) = 2³ + 1 = 8 + 1 = 9

f(3) = 3³ + 1 = 27 + 1 = 28

f(4) = 4³ + 1 = 64 + 1 = 65

range is {9, 28, 65 }

A triangle has two angles that measure 18.6 degrees and 113.4 degrees respectively. what is the measure of the third angle?
spin [16.1K]

Answer:

x = 48

Step-by-step explanation:

18.6 + 113.4 + x = 180

132 + x = 180

x = 180 - 132

x = 48
