The answer in the procedure
Step-by-step explanation:
we know that
The lateral area of a cone is equal to
where
r is the radius of the base
l is the slant height
we have
assume 
substitute the values
This value is an underestimate, because the assumed pi value is less than the real value
assumed value
real value 
1.527 is that one of the options?
Given that
attains a maximum at
, it follows that
at that same point. So integrating once gives
and so the first derivative is
.
Integrating again, you get
You know that this curve passes through the point (2, -1), which means when
, you have
:
and so
