Answer:
39.25 cubic feet of paint will be needed by Ellis.
Step-by-step explanation:
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.
hope this helps
0.75 is the possible answer, if not its probably 12 :)
Answer: 2 2/5
Step-by-step explanation:
You can do 6 * 2/5 = 2 2/5
OR
You can do 2 + 2 + 2/5
6/5 = 1 1/5 * 2 = 2 2/5
g(x) = 0.4x - 1.8
Since the output, or g(x), is 4.6, substitute that number in for g(x).
4.6 = 0.4x - 1.8
Add 1.8 to both sides of the equation.
4.6 + 1.8 = 0.4x - 1.8 + 1.8
6.4 = 0.4x
Now, divide 6.4 by 0.4.
The answer is x = 16. The output is also x.
