Question

A circular Garden has an area of approximately 153.86 square feet Iris wants to put a fence around the garden how much fencing does she need to enclose the garden explain how to apply the formulas for area and circumference of a circle to determine the length of fencing use 3.14 for pi

Answer 1

First, you need to find the diameter step by step
Step 1) divide the area by pi

153.86/3.14 = 4

Step 2) get the square root of 49

The square root of 49 is 7, so the radius is 7

Now, find circumference using c = $\pi d$

c=7(3.14)

3.14(7) = 21.98

21.98 square feet is the circumference (fencing)

I hope this helped
