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)

Suppose x 1 & x 2 are the point of maximum and the point of minimum respectively of the function f(x) = 2x 3 – 9ax 2 + 12a 2 x + 1 respectively, then for the equally x 2 1 = x 2 to be true...
 
 
The extreme points are attained at f ’(x) = 0 => 6x 2 – 18ax + 12a 2 = 0 => x = 2a, a f ’’(x) = 12x – 18a f ’’(x) 0 if x = 2a Hence the min at x = 2a = x 1 & max at x = a = x 2 The condition...
