Well, to find the circumference of a circle, we can use the formula
C=2
r.
So just plug in 3.5 into the formula.
C=2
3.5.
Multiply and we get C=21.99. which is about 22
So our answer would be C. 22 feet.
Hope I helped!
Answer: I think it’s the 2nd, 3rd and 4th
Step-by-step explanation:
Step-by-step explanation:
1)
S = {1<=x<=10}
where x = the recycle time.
2)
E1 = {1.5<=x<=5}
3)
E2 = {2<=x<=8}
4)
E1 U E2 = {1.5<=x<=8}
5)
E1 and E2 = {2<=x<=5}
6)
E1' = {1<=x<1.5} U {5<x<=10}
7)
E2' = {1<=x<2} U {8<x<=10}
Thus,
E1 U E2' = {1<=x<5} U {8<x<=10} [ANSWER]

0.000000109 in scientific notation will look as it follows:
1.09 * 10^-7
or
<span>
1.09 E-7
It's the same as 1.09 * (-10000000)
I hope it'll give you some clue of scientific notation with decimals.</span>
