Given:
Area of a circle, A=50.265 sq. units.
Radius of circle, r = 4 units.
To find:
The value of π to the nearest thousandth.
Solution:
Formula for area of a circle is
Now, using 
expression, we can find the value of π.
Approximate the value to the nearest thousandth (three digits after decimal).
Therefore, the approximated value of π is 3.142.
that is the solution to the simultaneous equation
A) let the number of cameras sold per day for breakeven be x
Total daily cost = 2000 + 9x
Total daily revenue = 17x
therefore for just covering expenses both cost and revenue must be equal
2000 + 9x = 17x
2000 = 17x - 9x = 8x
x = 2000/8 = 250 cameras
b) increasing production by 50 cameras per day will give a daily profit of;
50 * (17 - 9) = 50 * 8 = $400 (seeing that the fixed daily cost of $2000 remains unchanged)

Answer:
u1 = 1
u6 = 31
un = 1 + 6(n - 1)
Step-by-step explanation:
Sn = 3n² - 2n
u1 = S1
3(1)² - 2(1)
3 - 2
1
u6 = S6 - S5
[3(6)² - 2(6)] - [3(5)² - 2(5)]
96 - 65
31
un = a + (n - 1)d
u6 = a + 5d
31 = 1 + 5d
5d = 30
d = 6
un = 1 + 6(n - 1)
