Patricia wishes to have a rectangular-shaped garden in her backyard. she has 82 ft of fencing material with which to enclose her garden. letting x denote the width of the garden, find a function f in the variable x giving the area of the garden. what is its domain?

width=x

perimeter=80

or 2(x+l)=80

so l=length=40-x

so the area=x(40-x)

the area can never be 0

x(40-x)>0

this gives the domain as 0

Step-by-step explanation:

answer: -8.2562234e+13

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
