Answer: I believe the answer is around/about 56.55
Step-by-step explanation: C=2πr=2·π·9≈ 56.54 or aound 56.52
Formula: C=2πr
Simplified Equation:
2 x 3.14 x 9= 56.52 - 56.55
Good luck!! I hope this helps! All you have to do is memorize the formula, break down & simplify the numbers and equation and you're golden!!

Answer:
Emma
Step-by-step explanation:
Emma ran (3 1/2)×(1000 m) = 3500 m compared to Grace's 380 m. 3500 m is farther, so Emma ran farther.

Answer:
(x, y, z) = (x, x+2, 3x+1)
Step-by-step explanation:
We can add twice the second equation to the first to get ...
[eq4] -3x +0y +z = 1
Adding the first and second equations gives ...
[eq5] -x +y +0z = 2
Solving [eq4] for z gives ...
z = 3x +1
Solving [eq5] for y gives ...
y = x +2
Then the solution triple is (x, y, z) = (x, x+2, 3x+1).
If you would like to solve the equation above, you can do it this way:
1/3 * h - 4 * (2/3 * h - 3) = 2 - 3 * h - 6
1/3 * h - 8/3 * h + 12 = -4 - 3 * h
-7/3 * h + 3 * h = -4 - 12
-7/3 * h + 9/3 * h = -16
2/3 * h = -16
h = -16*3/2
h = -24
The result is -24.
This answer us 16.97
you do square root of 288 and it will give you the answer of 16.97
