Answer:
So, solution of the differential equation is

Step-by-step explanation:
We have the given differential equation: y′′+4y=5xcos(2x)
We use the Method of Undetermined Coefficients.
We first solve the homogeneous differential equation y′′+4y=0.

It is a homogeneous solution:

Now, we finding a particular solution.

we get

So, solution of the differential equation is

Answer:
29
Step-by-step explanation:
Answer:
Step-by-step explanation:
Formula
V pi * r^2 * h
Givens
r = 3 m
h = 6 m
pi = 3.14 when used.
Solution
V = pi r^2 * h
V = pi * 3^2 * 6
V = 9 * 6 * pi
V = 54 * pi Volume in terms of pi
V = 54*3.14 Volume using a value for pi
V = 169.56 to the hundred's place.
