Answer:
The value of m in the expression is 5
Step-by-step explanation:
Given expression as :
3 + ( 4 + 5 ) = ( 3 + 4 ) + m 
Or,  3 + ( 9 ) = ( 7 ) + m 
Or,  12  = 7 + m 
 ∴   m = 12 - 7 = 5 
Hence The value of m in the expression is 5   Answer 
 
        
             
        
        
        
Answer:
In terms of pi: 164.5pi cm squared
Substituting pi for 3.14: 516.53 cm squared
Step-by-step explanation:
