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.

Answer:123
Step-by-step explanation:
Answer:
The answer is d 1:2
Step-by-step explanation:
Since they are alternate interior angles, they will be congruent with each other.
4x= 5x-30
Subtract 5x on each side.
-1x= -30
Divide -1 into both sides.
x= 30
Now just plug in 30 too (4x) for the angle measure of both sides.
4*30 = 120
Each angle is equal to 120.
Hope this helps!
