Answer:
Step-by-step explanation:
The average value theorem sets: 
if f (x) is continuous in [a, b] and derivable in (a, b) there is a c Є (a, b) such that
 , where
 , where
f(a)=f(π/2)=-4*sin(π/2) = -4*1= -4
f(b)=(3π/2)=-4*sin(3π/2) = -4*-1 = 4

Answer:
D. 564.44 cm^3
Step-by-step explanation:
V = (1/3)(pi)r^2h
V = (1/3)(3.14159)(7 cm)^2(11 cm)
V = 564.44 cm^3
