Ans:
Using the inequality
m(b-a)\leq \int_{a}^{b}f(x)dx\leq M(b-a)
a = \pi , b = 3\pi
m\leq f(x)\leq M
Max. value of A
2\pi M
Min. value of A
2\pi m
You can easily find the m & M from f(x) (I am not finding b/c f(x) is not clear)

3 ∫ 2 (2x 2 + 1) dx
 
 
integration of (2(X^2)+1)dx from 2 to 3 is equal to (2((x^3)/3)+x) from 2 to3 =(2((3^3)/3)+3)-(2((2^3)/3)+2) =(2*(27/3)+3)-(2*(8/3)+2) =(18+3)-((16/3)+2) =(21)-(22/3) =41/3
