Circumference = 2pi * r
So
3pi = 2pi r divide away pi
3 = 2 r
(3/2) = r = 1.5 m
Area = pi ( r^2) = pi (1.5)^2 = 2.25 pi m^2 ≈ 7.07 m^2

Answer:


Step-by-step explanation:
Given

Solving (a): The cost function:
From the given parameter, it shows that the number of floor has no effect on the floors.
So, represent the floors with x.
The cost function is:

Solving (b): The slope and its interpretation
A function is represented as:

Where:

By comparing:
to 

So:

<em>What it means is that, no matter the number of floors, the cost remains unchanged.</em>
Answer:
The population that gives the maximum sustainable yield is 45000 swordfishes.
The maximum sustainable yield is 202500 swordfishes.
Step-by-step explanation:
Let be
, the maximum sustainable yield can be found by using first and second derivatives of the given function: (First and Second Derivative Tests)
First Derivative Test

Let equalize the resulting expression to zero and solve afterwards:


Second Derivative Test

This means that result on previous part leads to an absolute maximum.
The population that gives the maximum sustainable yield is 45000 swordfishes.
The maximum sustainable yield is:


The maximum sustainable yield is 202500 swordfishes.
Your answer will be negative 2
You need to distribute the 3, so your answer would be 6b-3
