First of all. I would like to formally apolagize to everyone, as my last question wasn't very informative or detailed and I am truly sorry for upsetting anyone. 


This is the question from my Pace:

The volume of a paint can is 215 in2. If the height of the can is 7.5 in, what is the radius to the whole number?


I have looked through my pace but I can't find anywhere where it properly explains this. Please help.

What's a "pace?" Is it a workbook, are you in a private school or something?

Pyscho Baker, I'm homeschooled, doing Distance Education, and my school sends me paces, It's basically a 10 - 50 page workbook, with lots of questions and all that stuff, but the thing is a lot of the stuff they explain very poorly cause they don't have space to put massive detailed instructions. it sucks.

Volume would normally be given as inches^3....I'm going to assume that it is supposed to be


215 in ^3


The paint can is a cylinder.....and the volume of a cylinder is


pi * radius ^2 * height


Filling in what we know, we have


215  = pi * radius^2 * 7.5      


Divide both sides by  pi *  7.5


[215 / ( pi * 7.5) ]  = radius^2


Take the square root of both sides


sqrt [  215 / (pi * 7.5) ]  =  radius  = about 3.02 inches  =  about 3 inches to the nearest whole number


Hope that helped....!!!



cool cool cool
