The left sum would be f0+f1+f2+f3
The right sum would be f1+f2+f3+f4
The trapezoidal rule value is:
(f0+f1)/2 + (f1+f2)/2+(f2+f3)/2 +(f3+f4)/2
This would put the trapezoidal rule in the middle , which makes the answer:
Lower sum < Trapezoidal rule Value < Upper sum
Answer:
A and b r the same but b is just under x line
C would be the answer cause if it was d it be under x line
Diameter = 2* the radius of a cylinder
radius is half the diameter of a cylinder
i.e. r = d/2
