The container is coated with 2 layers of specialty paint that costs $6.05 per jar

Question:

The container is coated with 2 layers of specialty paint that costs $6.05 per jar. Each jar pf paint covers 800cm2. How much does the paint cost?

Answers

So u use the formula for S.A which is 2*pi*r*h, but how do u know what shape the container is?.

You need to know the "container" area that you are covering. Divide that by 800 cm^2 for the number of jars per coating layer. Double that for two coats. Then take the next larger integer if there is a fraction left over.

Then multiply that integer number of jars by $6.05.

Could u help me set it up? like with the formula and everything? it's just a little confusing..

ANYYBODDYY plz it would be nice to know if someone had the knowledge to help me.

Your problem cannot be solved without the area. I have no idea what kind of container you are talking about. Somewhere along the line, you have not communicated all the information needed..

Anyone...? i need sleeppppp. plz tell me now if no one understands so i can go to bed and get in trouble for not finishing my homework tomorrow..

Plzzzz help!! thx..

Unless the problem states what the container shape is, you don't know..

What is the surface area of the container?.

If you use a net for the shape you can calculate one circular cercal then the second one then the rectangle then add it all up.
