Answer:
25.1 cubic meters
Step-by-step explanation:
The volume is given by ...
V = (1/3)Bh
where B is the area of the base.
B = πr² = π(C/(2π))² = C²/(4π)
Then the volume is ...
V = (1/3)(C²/(4π))h = C²h/(12π)
V = (9 m)²(11.7 m)/(12·3.14159) ≈ 25.1 m³
The volume of the cone is about 25.1 cubic meters.
If the company makes 1 canoe only, then the cost is, the fixed cost plus how much it costs for the 1 canoe, or
180,000 + 1*120
if it makes 2 canoes
180,000 + 2*120
3 canoes 180,000 + 3*120
4canoes 180,000 + 4*120
x canoes 180,000 + x*120
so... we dunno what "x" is, but whatever "x" maybe, the cost ends up as 180,000 + x*120, or 180,000 + 120x
now, let's see the revenue
1 canoe 1 * 240
2 canoes 2*240
3 canoes 3*240
x canoes x*240
so.. whatever "x" maybe, the Revenue is x*240 or 240x
break-even point is when, the amount of expenses and earnings cancel each other out, or, there's no profit, but there's no loss either, same amount that's spent is also earned back
so, the break-even point occurs when Revenue = Cost
180,000 + 120x = 240x <--- solve for "x"
Because you can’t simplify anymore within the parentheses you add the like terms a, b, and c
