Answer:
49.12 square inches 
Step-by-step explanation:
Area of a circle = Pi x r^2
 = 3.14 x 4^2
 = 3.14 x 16
 = 50.24
Half the circle = 25.12 squared inches
Area of a triangle = base x height /2
 = 6 x 8 /2
 = 24
25.12 + 24 = 49.12 square inches
 
        
                    
             
        
        
        
Answer:
V = 210 cm³
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = Ah ( A is the area of the base and h is the height )
Here A = 5 × 6 = 30 cm² and h = 7 cm , then
V = 30 × 7 = 210 cm³
