Charlize has a fence around her 15 foot by 20 foot garden.
If she decides to reconfigure her garden into a circle and she only wants to
use the fence she already has to enclose it,
what is the area of the largest possible circular garden charlize could create?
Express your answer as a decimal to the nearest hundredth.
:
Find the perimeter of the present garden
p = 2(15) + 2(20)
p = 70 ft of fence
:
This will be the circumference of the a round garden
Find the radius
2%2Api%2Ar = 70
r = 70%2F%282pi%29
r = 11.141 ft is radius
:
Find the area
A = pi%2A11.141%5E2
A = 389.93 sq/ft
