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

Step-by-step explanation:

We can work on the products of binomials using distributive property to multiply every term of the first binomial by every term of the second one. Finally combine like terms to get the trinomial that results:

1) $(2+a)(2+a)=4+2a+2a+a^2=4+4a+a^2$
