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

I believe it is 10x
Step-by-step explanation:
m=10x
b=-1
I learned this today on my math course titled, “slope y-intercept”
If it is wrong then it might be -1. Yet again I just learned this today!

Step-by-step explanation:
The error is that the factors of 3 and 21 are missing from the list for 63
Factors of 42 : 1, 2, 3, 6, 7, 14, 21, 42
Factors of 63 : 1, 3, 7, 9, 21, 63
common factors are : 1, 3, 7, 21
greatest common factor = 21
<span>choose any two points on the line.
draw a right-angled triangle with the line as hypotenuse.
use the scale on each axis to find the triangle's: vertical length. horizontal length.
work out the vertical length ÷ horizontal length.

the result is the gradient of the line.</span></span>
