7+5= 12 ones. Or one ten and 2 ones. They made 12.
        
                    
             
        
        
        
1/2 x 3/4 
1 x 3 / 2 x 4
= 3/8
        
             
        
        
        
Answer:
2310m^3
Step-by-step explanation:
base area which is the circle = πr^2
But diameter, d = 14, r = 14/2 = 7
area = π × (7)^2 = 22/7 × 49 = 22 × 7 = 154
Volume = base area × height
 = 154 × 15 = 2310
