As the new mathematical operation is defined by a△b=a^2-b/b-a^2, the value of 4△3 using the same operation will be 4△3 = -1
 
As per the question statement, we are given a new mathematical operation a△b=a^2-b/b-a^2 and we are supposed to find the value of 4△3 using the same operation.
Given, a△b=a^2-b/b-a^2
now 4△3 = (4^2-3) / (3-4^2)  
4△3 = (16-3) / (3-16)         
4△3 = 13 / -13  
4△3 = -1
Hence, as the new mathematical operation is defined by a△b=a^2-b/b-a^2, the value of 4△3 using the same operation will be 4△3 = -1.
- Mathematical operation: An operator in mathematics is often a mapping or function that transforms components of one space into elements of another.

Answer:
226.19
Step-by-step explanation:
area of a cylinder is 2 times pi times radius time height plus 2 times pi times radius squared 
radius=6/2=3
height=9
substitute in your values and get 226.19cm squared
