Suppose that you needed to make a pen for some small animals. You have 12.0 m of fencing. You decide to make a circular pen, because if you wish to enclose an area using a given length of fencing, then a circular fence encloses a larger area than a fence of any other shape. What is the area A of the pen

Step-by-step explanation:

Given

Required

Determine the area of the pen

The given parameter represents the perimeter of the pen;

Since, the pen is circular, we have circumference, C:

Substitute 12 for C

Divide through by 2

Make r the subject of formula

The area (A) of the pen is calculated as follows;

Substitute for r

Open Bracket

Take as 3.14
