Can someone explain why a is the right answer to this question? i'm unsure of how to work out this problem.

So firstly, we have to find the radius of the circular garden before finding the circumference (the amount of fencing needed to surround the garden). To find the radius, use the area formula (), plug in the area of the garden (36 ft^2) and solve for r as such:

So that we know the radius, plug that into the circumference equation () to solve:

Your answer is A. 12√π.

this is false ^.^ lol

the answer is d

hope this
