Answer:
V = pi * R^2 * h 
R = (V / (pi * h))^1/2 = (141.3 / (3.14 * 5))^1/2 = 3 cm 
 
        
             
        
        
        
To find percent error, you subtract the actual number from your estimate, take the absolute value, and divide by the actual number.
l 96 - 118 l
l -22 l
l 22 l
l 22 l / 118
0.19%  (this was rounded)
Hope this helps!
        
             
        
        
        
32+20=52 so there are 52 people in all. 
32/52  people are men.
we now have to subtract 1 from this fraction like so 32-1/52-1 since the magician took away 1 man from the audience (therefore reducing the amount of men as well as the audience as a whole) resulting in 31/51
we multiply 32/52 with 31/51 to get 248/663. simply turn this fraction into a percent by multiplying the quotient by 100 and rounding it to the nearest tenth to get 37.4%
        
             
        
        
        
Answer:
1. if x + 5 = 12, then x = 7
:Subtraction property of equality
2. If x + y = 20, and y = 5, then x + 5 = 20.
<u>:Substitution property of equality</u>
3. If 2x3 = 11, then 11 = 2x - 3.
<u>:Symmetric property of equality</u>
 
        
             
        
        
        
You got the equation correct
