Answer:
about 56.55 (rounded)
Step-by-step explanation:
diameter = 2r
circumfrence = dimeter(pi)
18(pi)
= about 56.55 (rounded)
To find out what 2 miles minus 3,333 yards is, first what you have to do is convert one unit to the other. I decided to convert 2 miles into yards. What you can do is multiple how ever many yards is one mile by two. So, there are 1,760 yards in 1 mile. 1,760 x 2 is 3,520. So now we have to subtract 3,520- 3,333.
The answer is 187.
To solve this, we are going to multiply our degrees by a conversion factor. Remember that 1°=

, so to convert -40° to radians, we are going to multiply -40° by the conversion factor

; that way we can cancel degrees and express our answer in radians:
(-40°)

We can conclude that the correct answer is:

I'm not sure if this is right. I didn't feel confident with my answer.
Hello from MrBillDoesMath!
Answer:
a(n) = 12 - 3(n-1) , n = 1,2,3.,,
Discussion:
The terms are 12, 9, 6, 3 so we are apparently subtracting 3 from each succeeding term. . Hence
a(n) = 12 - 3(n-1) , n = 1,2,3.,,
Thank you,
MrB
