90miles/hour
divide by 360 to convert to miles per second
multiply by 5280 to get to feet per second
multiply by number of seconds to get length (in feet) of each object

Step-by-step explanation:
The formula for the volume of a sphere is V = 4/3 πr³.
So 
Given
Volume (v) = 57ft³






![r =  \sqrt[3]{13.6}](https://tex.z-dn.net/?f=r%20%3D%20%20%5Csqrt%5B3%5D%7B13.6%7D%20)
Therefore r = 2.4 ft 
I gave my answers by rounding off. so if you don't round off then it's answer is 2.3 ft
 
        
             
        
        
        
Answer:

Step-by-step explanation:
Given the initial ratio of 3 parts water to 5 parts fruit juice, you can set up a proportion (equivalent ratios) to determine the amount of water needed with just 1 part of fruit juice: 

cross multiply: 5x = 3
divide: 5x/5 = 3/5 or x = 3/5 
3/5 = 0.6 parts water
