The average value is

#### Explanation:

The average value of a function continuous on

#A = 1/(b - a) int_a^b f(x) dx#

Thus

#A = 1/(2pi - 0) int_0^(2pi) x + sinx#

#A = 1/(2pi) [1/2x^2 - cosx]_0^(2pi)#

#A = 1/(2pi)(1/2(4pi^2) - 1 + cos(0))#

#A = 1/(4pi)(4pi^2)#

#A = pi#

Hence, the average value of the given function on the interval
