It’s bevause you can see what you are doing instead of doing it all of your head which could get messed up.
(1) circumference of a circle = 2π.R
(2) area of a circle = π.R²
Area = 452.16 m² (given), so we can calculate the radius:
452.16 = π.R²
452.16/π = R²
143.92 = R² → R =√143.92 ≈ 12 m
Having R = 12, now we can calculate the circumference :
circumference of a circle = 2π.R = 2.π.12 = 75.41 m
Answer:
y < 2X - 1
y = 2X - 1
Step-by-step explanation:
Let's try to make an equation from the worded problem.
"is Less than " means <
2 times means 2 * X
= 2X
y < 2X - 1
y = 2X - 1
7) y = 4x
8) y = 7x/8
9) y = 25x/3
I think this are the answers.
