Answer:
y2 = (6x + 7)/36 + (Dx + E)e^x
Step-by-step explanation:
The method of reduction of order is applicable for second-order differential equations.
For a known solution y1 of a 2nd order differential equation, this method assumes a second solution in the form Uy1 which satisfies the said differential equation. It then assumes a reduced order for U'' (w' = U'').
The differential equation becomes easy to solve, and all that is left are integration and substitutions.

Answer:
11.81pi
Step-by-step explanation:
r^2=25pi
r=8.86
length=2pi(8.86)(240/360)
=17.72pi(2/3)
=11.81pi
