Hello!
To find the area of a circle you do

the "r" stands for radius which is half the diameter
So we do

Which gives us the answer of 314.16
Hope this helps!

Answer:
Step-by-step explanation:
Let's use the definition of the Laplace transform and the identity given:
with
.
Now,
. Using integration by parts with u=e^(-st) and dv=cos(5t), we obtain that
.
Using integration by parts again with u=e^(-st) and dv=sin(5t), we obtain that
.
Solving for F(s) on the last equation,
, then the Laplace transform we were searching is
Answer:
First option: (Substitute)
2x+3 (x+1.5) = 12
