Answer:
About 28.26 inches.
Step-by-step explanation:
The formula for circumfrence is c = 2(pi) * r.
We know that r = 4.5 (because the diameter is 9 inches).
So, the equation is c = 2(pi) * 4.5
Let's solve:
c = (2*3.14) * 4.5
c = 6.28 * 4.5
c = 28.26
Therefore, the final answer is 28.26 inches.
Of course, this is not exact because pi is irrational and goes on forever, but the question is asking for an estimate anyways.
Maybe you can do 8 divided by 2 would equal 4 or you can do equations that equal 8.
Answer:
(1, -3)
Step-by-step explanation:
Start where the axes meet. That is the origin (0,)
Move 1 place to the right that is the x coordinate
Move 3 places down that is the y coordinate
(1,-3)
(t2 - 8t - 7) - (t2 + 5t - 6)
=t2 - t2 - 8t - 5t - 7 + 6
= -13t-1
