Answer:
Pick the best solution.
Step-by-step explanation:
Volume of a cone is V = ⅓πr²h
If cone diameter is 4.3
V = ⅓π(4.3/2)²(5.2) = 25.17148... ≈ 25.17 ft³
If cone radius is 4.3
V = ⅓π(4.3)²(5.2) = 100.685950... ≈ 100.69 ft³
If cone diameter is 5.2
V = ⅓π(5.2/2)²(4.3) = 30.439938... ≈ 30.44 ft³
If cone radius is 5.2
V = ⅓π(5.2)²(4.3) = 121.75975... ≈ 121.76 ft³

Step-by-step explanation:
negative integers are still rational numbers if it is a whole number or complete
 
        
             
        
        
        
The additive inverse of 7/2 would be -7/2 (option B) Since its. opposite !
A)is the additive inverse of C) ; C) is the additive inverse of A) (not your answer)
B. is the additive inverse for this problem (7/2) so thats how we found that this is your answer (answer)
D is the same thing for the problem (7/2) (not your answer) 
7/2 isnt the additive inverse for 7/2 because they are the SAME not the opposite.
+ = - (Positive = negative)
- = + (negative = positive)
