Answer: 617 ft.
Step-by-step explanation: So first, the formula is A=C²/
4π, knowing this, let's just plug in our numbers
A = C² / 4 · π
A = 88² / 4 · 3.14
A = 7744 / 4 · 3.14
A = 7744 / 12.56
A = 7744 / 12.56
A = 616.56
A ≈ 617
Hope this helps :)
For rounding to the nearest 10, you look at the 1's place and determine if its over 5 or under 5. If it is under 5 you round down to the nearest ten, and if its over you go to the nearest ten. For 407, 7 is over 5, so it is 410.
Answer:
5(x² - 4)
Step-by-step explanation:
5x² - 20
5 can divide both 5 and 20, 5x²/5 and -20/5 = x² and -4
5(x² - 4), to know if you are correct, multiply 5 by the bracket and you get the question back
Answer:
if it is straight line it's a linear
Answer:
I think it should be: P = (85-71)/(85-66) = 14/19
