Answer:
12.5 pie , 39.25 using pie=3.14, and 39.28 to be exact
Step-by-step explanation:
BTW n=pie
10in= Diameter
5in=Radius
Area=n5^2
= 25n/2
=12.5n
12.5 times 3.14= 39.25
22/7 times 12.5= 39.2857143
Answer:
A
Step-by-step explanation:
You would first subtract 6x from both sides which will give you something like:
-4= 2x - 9
then you would add 9 on both sides which would give you
5 = 2x
which now you would divide 2 by both sides with would give you
5/2 = x
simplify it one more time
2.5 = x
Answer:
we conclude that:

Step-by-step explanation:
Given
We have to determine 
so

Thus we conclude that:

1700m = 40 mins
60 mins = 1 hour
60 mins - 40 mins = 20 mins (Half of more)
1700 / 2 = 850
1700 + 850 = 2550 meter/hour
Answer:
4*10^18
Step-by-step explanation:
Easier to think of it as the factors out front (8 / 2) = 4
and subtract the exponents 30 - 12 = 18
= 4*10 ^18
