Arc/(2πr)=α/360
α=360*arc/(2πr)
α=180*arc/(πr), since arc=12 and r=12
α=2160/(9π)°
α=240/π°
α≈76.39° (to nearest one-hundredth of a degree)
Well we know that:
1-4 stay on the floor,
5-9 it's round up time.
So with that in mind you would round the 9's up and they would round up th 4 to a 5. 5's round up so that would round up the first 4 to a 5.
SO your answer would be 5,000.

Answer:
B
Step-by-step explanation:
Both of the two numbers should equal the same amount when dividing.
For example, in A
25÷15=1.666...
30÷18=1.666...
Both of these answers are the same so that means that 25/30 is equivalent to 15/18
When you're dividing B though, they don't equal the same amount
90÷15=6
105÷18= 5.833...
that means that 90/105 does NOT equal 15/18
good luck
