Answer:

Step-by-step explanation:
Convert the mixed number to the fraction:

METHOD 1:

METHOD 2:

I'll answer and explain, its pretty much the last question. Easy way to put it,
1 and 4 are diagonal from each other so they are the same number.
1 and 4 = 120
2 and 3 are diagonal so they both = 60
Same thing for the bottom
1=120
2=60
3=60
4=120
5=120
6=60
7=60
8=120
Volume of a cylinder is pi*r^2*h where r = radius and h = height
so 3^2*6*pi = 9*6*pi = 54pi
54 pi is the answer. mark me brainliest please!
The second result is more precise because it's in millilitre,so if the first were to be fully precise,it should have been 78.6 cm.
Hope this helps!
Answer:
(-∞, -4] ∪ [5, ∞)
Step-by-step explanation:
Hi!
Alright, so greater (or less) than or equal to is denoted with a bracket.
If x is less than or equal to -4, then the bracket is on the left side.
(___, -4]
Because x is <em>any</em> number under or equal to -4, x can range from negative infinity. However, we use a parentheses for infinity because infinity can never truly be reached.
So, x
-4 = (-∞, -4]
X
5
Equal to = bracket
X is any number above 5, so
[5, ∞)
Because we want both of these, we use the union sign (∪)
so,
= (-∞, -4] ∪ [5, ∞)
