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

The value of w varies directly with z. If z = 4, then w = 12. What is the value
IrinaVladis [17]

Answer:

18

Step-by-step explanation:

w varies directly with z, let k be the constant of proportionality, hence this can be represented by the equation:

w = kz

When z = 4, w = 12, hence we need to find the value of the constant of proportionality, substituting:

12 = 4k

Dividing both sides by 4:

12/4 = 4k/4

k = 3

Therefore the equation becomes:

w = 3z

The value of w when z = 6 is given as:

w = 3(6)

w = 18

A bus traveled on a level road for 4 hours at an average speed of 20 miles per hour faster than it traveled on a winding road. T
Kruka [31]

To solve this problem, we must recall that the formula for velocity assuming linear motion:

v = d / t

Where,

v = velocity

d = distance

t = time

 

For condition 1: bus travelling on a level road

v1 = d1 / t1

<span>(v2 + 20) = (449 – d2) / 4                        --->1</span>

 

For condition 2: bus travelling on a winding road

v2 = d2 / t2

<span>v2 = d2 / 5                                            --->2</span>

 

Combining equations 1 and 2:

(d2 / 5) + 20 = (449 – d2) / 4

0.8 d2 + 80 = 449 – d2

1.8 d2 = 369

d2 = 205 miles

 

Using equation 2, find for v2:

v2 = 205 / 5

v2 = 41 mph

 

Since v1 = v2 + 20

v1 = 41 + 20

v1 = 61 mph

 

Therefore <span>the average speed on the level road is 61 mph.</span>

Given g(x) = -X – 1, solve for x when g(x) = 3.
Vika [28.1K]

Answer:

-4 = x

Step-by-step explanation:

g(x) = -X – 1

g(x) = 3

3 = -x-1

Add 1 to each side

3+1 = -x-1+1

4 = -x

Multiply by -1

-4 = x
