Answer:

Step-by-step explanation:
apply the inverse properties of logarithmic and exponential functions to simplify

all logs has base 'e'
Inverse property of log says that
, the value of ln e=1
we apply this property in our problem. ln has same base 'e' . ln and 'e' gets cancelled


A = pi(r)^2
diameter is 18in, so radius is 9in
= pi(9)^2
A = 254.469 (round is needed)
It's undefined, but I think you spelled it wrong.
