I think it is 142cm^2. What I did to work this out is, 236 divided by 5= 47.2 ( to get the surface area of a 1cm cylinder) then multiply by 3 = 141.6 then round
Answer:
11,872
Step-by-step explanation:
2,022+50=2,072+800=2,872+9,000=11,872
For this item, we represent the very original value or price of the given item by x such that increasing the retail price by 40 percent will give us 1.4x. Also, when the retail price of the item is reduced by 25 percent, we have.
new retail price = 1.4x (1 - 0.25) = 1.05x.
This means that the new retail price is only 5% over the manufacturer price.
Let the unknown be n, then:
n × 3 = 8 × 2
n × 3 = 16
n = 16 ÷ 3
n = 5.333
Because Z is directly proportional to X and inversely proportional to Y, therefore

where k = constant.
When X = 15 and Y = 9, Z = 5. Therefore
k(15/9) = 5
k = 5*(9/15) = 3
That is,

When X = 23, and Y = 14, obtain
Z = (3*23)/14 = 4.9286
Answer: Z = 4.929 (nearest thousandth)
