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

Step-by-step explanation:
welp
K>7/3 i dont know what the other box at the top is for so i cant answer that one
First, identify what fracion of an hour Larre spent outside using the model.
Since the square is divided in 4 equal parts, then the denominator of the fraction that Larre wants to represent is 4.
On the other hand, since 2 of those 4 parts are colored, then the numerator of the fraction that Larre wants to represent is 2.
Then, the fraction represented by the visual model is:
To find the answer, find an equivalent fraction by multiplying both the numerator and the denominator by 2:
Therefore, an equivalent fraction that can be made by multiplying the numerator and denominator by 2, is:
The correct choice is option C) 4/8.
Answer:
25 %
Step-by-step explanation:
The population has increased from 1000 to 1250 in a small town in USA.
It is asked to calculate the percentage of increase in the population of that place.
Now, the increase in population is given by (final population - initial population) =1250-1000 =250.
Therefore, the percentage increase in the population will be given by (increase in population/ initial population) ×100 %
=(250/1000)×100 %
=25 % (Answer)
