If the radius for the whole circle is 8 then half of it would be four. But if half of the circle is 8 then it would be 16pi for circumference if that's what you're trying to find.
Answer:
see below
Step-by-step explanation:
The costs are
2230.80 + .03 b where b is the board foot
the income was 1.13b
Profit is income - costs
Profit = 1.13b - (2230.80 + .03 b)
Distribute
= 1.13b - .03b - 2230.08
= 1.10b - 2230.08
Profit is when the money is greater than 0
(breaking even is 0)
0 <1.10b - 2230.08
Add 2230.08 to each side
2230.08 < 1.10b - 2230.08 + 2230.08
2230.08 < 1.10b
Divide by 1.10
2230.08/1.10 < 1.10b/1.10
2027.345455 <b
They must sell at least 2027.345 board feet of lumber per day to make a profit
