Area ( If you know the circumference) :
C^2 / (4×3.14) Brackets are important!
So you have to type :
53.38^2/(4×3.14)
= 226.865
Answer:
A
Step-by-step explanation:
x² - 3x - 54 = 0
x² - 9x + 6x - 54 = 0
x(x - 9) + 6(x - 9) = 0
(x - 9)(x + 6) = 0
x = -6,9
3+8+10+14+11= 46
46/(how many trees) 5= 9.2
9.2 years is your answer.
I would say 18 hours or basically 1080 minutes or basically <span>64800 seconds</span>
