Scenario : A Cylindrical Structure measuring 25 m tall, with a radius of 3 m has a major pest problem. You Decided to fog at a rate of 25 ml/100m3. Your forger has a tank size 4 L is calibrated to apply 100 mL/ minute .

Q 1 : How Many Milliliters of pesticide product are required to treat this structure?




Q 2 : How many tanks will you use to treat the area ?




Q 3 : What is the Volume of the Structure?



Q 4 : How many minutes will it take to fog the structure ?

What is the formula for the volume V of a cylinder with height h and radius r? (Hint: If you haven't memorize the formula yet, do so now.)

What is the volume V of this cylinder? (Hint: Plug into the formula.)

How many millimeters then are needed? (Hint: Set up the proportion; solve.)

Given the volume needed, how many tanks are needed? (Hint: Divide.)

As was pointed out in a previous reply, this was information that you needed to find for Q1.

Given the needed volume and the given rate, how many minutes are needed? (Hint: Set up the proportion; solve.)

If you gert stuck, please reply showing your thoughts and efforts so far. Thank you! ;)

Thank you

Stuck in Q2 : Which volume to divide on what ?
Q 4 : Given Volume ? ,

Very weak in trigonometry
 
First off, I'm not sure if you still need help, as this post got lost in the shuffle for several days. That said, let's look at Q2 and Q4. I'm assuming, since you specifically asked for help on Q2 and Q4 that you have solved Q1 and Q3 successfully.

"Q2 : How many tanks will you use to treat the area?"

When you solved Q3, what volume did you get for the cylinder? That answer is in cubic meters (m^3), so you'll need to convert it to liters (L). Use the known conversion rate 1 cm^3 = 1 ml. What, then, is the volume of the structure, in liters? And what is the volume of your tank, as given by the problem? So, how many tanks will you need?

As a hint, consider a simpler problem. Suppose the structure was a cube, measuring 2m x 3m x 4m. And suppose the volume of your tank was 2 liters. Then how many tanks would you need? Can you apply similar logic to the actual problem?

"Q4 : How many minutes will it take to fog the structure?"

When you solved Q1, what answer did you get for the number of ml needed? What is the rate at which you can spray, as given in the problem? Then, how many minutes would it take to complete the job?
