22 would be the answer. You reverse the equation so you multiply 3 and add 7   5x3 = 15  15+7= 22
        
                    
             
        
        
        
A=3.14r^2
A=3.14 x 10^2
A=3.14x100
A=314
314cm is your answer
        
             
        
        
        
Answer:
37ft³
Step-by-step explanation:
Volume of the fish tank = length × width × height = 5ft × 3ft × 3ft = 45ft³
Volume of the cubic stone = length × length × length = (2ft)³ = 8ft³
Volume of the water = volume of the fish tank - volume of the cubic stone
i.e Volume of the water = 45ft³ - 8ft³ = 37ft³
