I would think 3? it should be 3 because 32*2=64 which isn’t everyone 32*3 is 96
79+12=91

Answer:
8 π .
Step-by-step explanation:
 radius increases at a constant rate of 1 in/sec.
dr / dt = 1 
where r is radius .
radius after 4 sec
 r = 1 x 4 = 4 in
area A = π r²
differentiating both sides 
dA / dt = 2 π r dr / dt 
Putting dr / dt  = 1 , r = 4 in
dA / dt = 2 π x 4 x 1 
= 8 π sq in per sec. 
Area increases at the rate of 8 π per sec. 
 
        
             
        
        
        
Answer:
no
Step-by-step explanation:
To be a function, the x values must correspond to one and only one y value.
In the coordinates given, (0.3, 0.6) and (0.3, 0.7) have the same x- value.
That means that they cannot be a function.
