Ellis is painting wooden fenceposts before putting them in his yard. They are each 5 feet tall and have a diameter of 1 foot. Th
Naya [18.7K]

Answer:

39.25 cubic feet of paint will be needed by Ellis.

Step-by-step explanation:

Volume of a cylinder:

The volume of a cylinder of radius r and height h is given by:

V = \pi r^2h = 3.14r^2h

How much paint will Ellis need to paint all the surfaces of the 10 fenceposts?

This is the combined volume of these 10 fenceposts.

They are each 5 feet tall and have a diameter of 1 foot.

Radius is half the diameter, so r = \frac{1}{2} = 0.5. Also h = 5

10 fenceposts:

Each has the same volume, so:

V = 10(3.14)r^2h = 31.4(0.5)^2(5) = 39.25

39.25 cubic feet of paint will be needed by Ellis.

X<9
The answer is x<9 because you first subtract 4 from both sides then divide both sides by -3. Which then would give you 9.

The sum of three consecutive integers is -206 . What is the largest integer?
solniwko [45]

Answer:

Can' possible......

Step-by-step explanation:

Let suppose the numbers are:

x

x + 1

x + 2

Now according to given condition:

x + x +1 + x+ 2 = -206

By adding we get:

3x + 3  = -206 Subtracting 3 from both sides:

3x + 3 - 3 = -206 -3

Both terms on right side have negative sign so we will add them. (answer will have negative sign.)

3x = -209  

Dividing both sides by 3:

x = -209/3

x = -69.6666

that is not an integer so the question is wrong.

I hope it will help you!

the amount of military spending M (in billions of dollars) in the U.S. during year t is given approximately by the equation M=48
Fynjy0 [20]

Answer:

2008

Step-by-step explanation:

M = 48.81t + 304.30

M = 694.78                            Solve for t

694.78 = 48.81t + 304.30     Subtract 304.30 from each side

390.48 = 48.81t                    Divide each side by 48.81

t = 390.48/48.81  

t = 8.00 yr

=====

Year = 2000 + t

Year = 2000 + 8.00

Year = 2008

Military spending hit $694.78 billion at the end of 2008.
