Pilaf has a circular garden plot with an area of 125 square feet. To fence the area, how many feet of fencing does she need?

1 answer:

8 0

So, to find the find the amount of fencing required, or the circumference of the gardening, pot...

Area = pi * r^2
125 square feet = pi *r^2
125/ pi = r^2
39.79 = r^2
root square of 39.79 = r
6.31 = r

To find the circumference, the formula is: pi * D (or Pi * r * 2)

therefore,

C = pi * 6.31 *2
C = 39.65 feet

therefore, 39.65 feet of fencing is needed.

hope this helps
