It is asking you to move the right formula with its match.
Formula for a cylinder: π*R^2*HSo the first option goes to the first shape.Example: 
Radius=5
Length=10
π≈3.14
3.14*5²*10
=725 cm³ for the answer. 
Formula for a square: l*w*hSo the 4th option goes with the 2nd shape. Example: l=5 w=5 h=5
(Length * Width * Hieght) 
5*5*5=125 for the answer.
Formula for a cone is: 1/3π*r^2*hSo the second option goes to the 3rd shape. 
Example: r=3 h=11 
π≈3.14

33 is your answer. 
Formula for the pyramid would be: 1/3*b*hSo the 3rd option would go to the 4th shape.Example: 
b=2 h=10

Rounded: 6.6
Hope this helps!~

Answer:
![\sqrt[3]{a^{2}+b^{2}}=(a^{2}+b^{2})^{\frac{1}{3}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Ba%5E%7B2%7D%2Bb%5E%7B2%7D%7D%3D%28a%5E%7B2%7D%2Bb%5E%7B2%7D%29%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D)
Step-by-step explanation:
∵∛x = (x)^1/3
∴ ![\sqrt[3]{a^{2}+b^{2}}=(a^{2}+b^{2})^{\frac{1}{3}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Ba%5E%7B2%7D%2Bb%5E%7B2%7D%7D%3D%28a%5E%7B2%7D%2Bb%5E%7B2%7D%29%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D)
So you can replace the radicals by fractional exponents
 
        
                    
             
        
        
        
Answer:
x = 15
Step-by-step explanation:
x/3 + 10 =15
Subtract 10 from each side
x/3+10-10 =15-10
x/3 = 5
Multiply each side by 3
x/3*3 = 5*3
x=15
 
        
             
        
        
        
175 shoppers didn't complete the survey
245 x 2/7= 70
245-70= 175
 
        
             
        
        
        
Let's write this proportion of equivalent ratios in equation form and then plug in our two known values to determine our two unknown values:
    (s1)2 : (s2)2 = A1 : A2
    (10)2 : (7)2 = 100 : 49
 
Ratio of the Areas = 100 : 49
