Volume Of Cylinders, Cones, And SpheresI NEED HELP ASAP!!

Answers

Answer 1

Answer:

8) 144pi

9) 196pi

11) 18pi

12) 298.67pi

Step-by-step explanation:

Cylinders

The volume of a cylinder is [tex]V = \pi r^{2} h[/tex], where r represents the radius of the base and h represents the height.

For the first cylinder, the radius of the base is 4 and the height is 9.

[tex]V = \pi (4)^{2} (9)\\V = \pi(16)(9)\\V = 144\pi[/tex]

For the second cylinder, the diameter is 6 and the height is 2. Since the radius is half the diameter, the radius is 3.

[tex]V = \pi (3)^{2} (2)\\V = \pi(9)(2)\\V = 18\pi[/tex]

Sphere

The volume of a sphere is [tex]V = 4\pi r^{2}[/tex], where r is the radius of the sphere.

The diameter is 14, meaning the radius must be 7.

[tex]V = 4\pi (7)^{2} \\V = 4\pi (49)\\V = 196\pi[/tex]

Cone

The volume of a cone is [tex]V = \pi r^{2} (h/3)[/tex], where r is the radius and h is the height.

The radius is 8, and the height is 14.

[tex]V = \pi (8)^{2} (14/3)\\V = \pi (64) (14/3)\\V = \frac{896}{3} \pi\\V = 298.67\pi[/tex]

Sean wants to make a beaded necklace 16 1/2 inches long. If each bead is 3/4 in wide how many beads does he need?​

Answers

Answer:

22 beads

Step-by-step explanation:

You need to divide 16 1/2 by 3/4.

16 1/2  /  3/4 =

= 33/2  /  3/4

= 33/2 * 4/3

= (33 * 4)/(2 * 3)

= 11 * 2

= 22

Answer: 22 beads

The drama club sold bags of candy and cookies to raise money for the spring show. Bags of candy cost $8.00, and bags of cookies cost $2.50, and sales equaled $33.50 in total. There were 5 more bags of cookies than candy sold. Find the number of bags of candy and cookies sold by the drama club

Answers

Answer:

Number of bags of candy = 2

Number of bags of cookies = 7

Step-by-step explanation:

Let, number of bags of candy = X

So, Number of bags of cookies = X + 5

Cost of candy bag = $8

Cost of cookies bag = $2.5

Total sales = $33.50

So, Total cost of Candy Bags + Total cost of cookies bags = Total sales

= 8X + 2.5 ( X +5) = 33.50

= 8X + 2.5X + 12.5 = 33.50

= 10.5X = 33.50 - 12.5

= 10.5X = 21

X = 2

So, number of bags of candy = 2

Number of bags of cookies = 2 + 5 = 7

A kayaker traveled 4 5/6 miles during the first hour, and 1 1/3 miles more then the next hour. How far did he travel in 2 hours

Answers

Answer:

11 miles

Step-by-step explanation:

Given that :

Distance traveled in first hour = 4 5/6 miles

Distance traveled in the next hour = 4 5/6 + 1 1/3

Therefore, the total distance traveled in 2 hours equals :

4 5/6 miles + (4 5/6 miles + 1 1/3 miles)

29/6 + 29/6 + 4/3

L. C. M of denominator = 6

(29 + 29 + 8) / 6

= 66 / 6 miles

= 11 miles

Find the volume of the cylinder in terms of x and to the nearest tenth

Answers

Answer:

12.57 in^3

Step-by-step explanation:

The easiest way to do this is to find the area of the circle surface and multiply it by the height

to find area the formula is pi r^2 and we are given the radius

so we plug in pi(2^2)=pi(4)= roughly 12.57

then we multiply the area by the height which is 1 so it would be the same

12.57(1)=12.57

From Message Regarding Labor Legislation (March 25, 1908)by Theodore Roosevelt I call your attention to certain measures as to which I think there should be action by the Congress before the close of the present session. There is ample time for their consideration. As regards most if not all of the matters, bills have been introduced into one or the other of the two Houses, and it is not too much to hope that action will be taken one way or the other on these bills at the present session. In my message at the opening of the present session, and, indeed, in various messages to previous Congresses, I have repeatedly suggested action on most of these measures. Child labor should be prohibited throughout the Nation. At least a model child-labor bill should be passed for the District of Columbia. It is unfortunate that in the one place solely dependent upon Congress for its legislation there should be no law whatever to protect children by forbidding or regulating their labor. I renew my recommendation for the immediate reenactment of an employers' liability law, drawn to conform to the recent decision of the Supreme Court. Within the limits indicated by the court, the law should be made through and comprehensive, and the protection it affords should embrace every class of employee to which the power of the Congress can extend. In addition to a liability law protecting the employees of common carriers, the Government should show its good faith by enacting a further law giving compensation to its own employees for injury or death incurred1 in its service. It is a reproach to us as a Nation that in both Federal and State legislation we have afforded less protection to public and private employees than any other industrial country of the world. I also urge that action be taken along the line of the recommendations I have already made concerning injunctions2 in labor disputes. No temporary restraining order should be issued by any court without notice; and the petition for a permanent injunction upon which such temporary restraining order has been issued should be heard by the court issuing the same within a reasonable timesay, not to exceed a week or thereabouts from the date when the order was issued.1. to bring on oneself2. bans10Select the correct answer.How does Roosevelt support his position that employees should receive compensations in case of an injury or death in paragraph 4?A.
