Sally plans to enclose a square garden with fencing. The area of the garden is 1600 square feet. How many feet of fencing does she need to enclose the garden? A. 160 feet
B. 40 feet
C. 800 feet
D. 320 feet

160 ft

Step-by-step explanation:

the length of one side would be √1600 which is 40 so 40• 4 is 160

its b

step-by-step explanation:

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 !
