Answer:
p=6.2
Step-by-step explanation:
 
        
                    
             
        
        
        
5a - 10*3 = 45
5a - 30 = 45
5a = 45 + 30
5a = 75
a = 15
        
                    
             
        
        
        
Answer:
235or 236
Step-by-step explanation:
A cone has a radius of 5 cm
 a height of 9 cm
Volume of cone =1/3πr^2h
 =1/3×3.14×5×5×9
 = 3.14×25×3
 =3.14×75
 =235.5
 =235or 236 is the answer
