S A = r² π + 2 r π h
192 π = r² π + 2 r π h   / : π
192 = r² + 2 r h
2 r h = 192 - r²
h = (192 - r² ) / 2 r 
V = r² π h = r² π ( (192 - r² ) / 2 r ) =
= π / 2 ( 192 r - r³ ) 
        
             
        
        
        
Answer:
79°c - (-3°c) = 82°c
Step-by-step explanation:
this is because we need to calculate the total gap between those numbers through number line. I have attached the photo, have a look over there.
