Answer:
Rob saved $24 on Saturday.
Step-by-step explanation:
Given:
Rob is saving to buy a new MP3 player.
Money earned in baby sitting = $11
Money saved =$6
First we will find the Percentage of amount he saved.
Percentage of amount he saved can calculated by Amount saved divided by total money earned and then multiplying by 100.
framing in equation form we get;
Percentage of amount he saved = 
Now Given:
Money earned in babysitting on Saturday = $44
We need to find the Money he saved on Saturday.
Money Saved can be calculated by Percentage of amount he saved multiplying by Money earned in babysitting on Saturday and then divided by 100.
framing in equation form we get;
Money Saved on Saturday = 
Hence Rob saved $24 on Saturday.
 
        
             
        
        
        
12 4/9 + 1 2/9=13 6/9+3 5/9=16 11/9 that answer is farther simpled 17 2/9
so the final answer is 17 2/9
        
             
        
        
        
Short answer: r = 8
Remark
The easiest way to do this is to solve the sphere's volume in terms of pi. When you do this, you can equate that to the formula for a cylinder and cancel the pi values. 
Step One
Find the volume of the sphere.
<em>Givens</em>
r = 6 cm
<em>Formula</em>
V = (4/3) pi r^3
<em>Sub and Solve</em>
V =  4/3 pi * 6^3
V = 288 * pi
Step two 
Find the radius of the cylinder
<em>Givens</em>
V = 288* pi cm^3
h = 4.5 cm
<em>Formula</em>
V = pi r^h
<em>Sub and solve</em>
288 pi cm^3 = pi r^2 * 4.5    Divide both sides by pi
288 cm^3 = 4.5 r^2              Divide both sides by 4.5
388 / 4.5 = r^2
64 = r^2                                Take the square root of both sides.
r = square root( 64)
r = 8 <<<<< Answer
