Answer:
f[g(4)] = 4
Step-by-step explanation:
Given table:

f[g(4)] is a composite function. 
When calculating <u>composite functions</u>, always work from inside the brackets out.
Begin with g(4):  g(4) is the value of function g(x) when x = 4.
From inspection of the given table, g(4) = -6
Therefore, f[g(4)] = f(-6)
f(-6) is the value of function f(x) when x = -6.
From inspection of the given table, f(-6) = 4
Therefore, f[g(4)] = 4

Answer:
The surface area of right regular hexagonal pyramid = 82.222 cm³ 
Step-by-step explanation:
Given as , for regular hexagonal pyramid :
The of base side = 3 cm
The slant heights = 6 cm
Now , 
The surface area of right regular hexagonal pyramid = 
Where a is the base side 
And h is the slant height
So, The surface area of right regular hexagonal pyramid = 
Or, The surface area of right regular hexagonal pyramid = 
Or,  The surface area of right regular hexagonal pyramid = 23.38 + 9 ×  
 
∴  The surface area of right regular hexagonal pyramid = 23.38 + 9 × 6.538
I.e The surface area of right regular hexagonal pyramid = 23.38 + 58.842
So,  The surface area of right regular hexagonal pyramid = 82.222 cm³ Answer
 
        
             
        
        
        
Answer:
314
Step-by-step explanation:
get out now 
So you divide the diameter by 2 to get the radius which would give you 10. Then multiply the radius twice so 10×10=100 thrn multiply by pi. 100x3.14=3.14
