Step-by-step explanation:
we know that
<u><em>The circumference of a circle is equal to</em></u>
or
where
D is the diameter and r is the radius
therefore
or
The number pi is the ratio circumference - diameter or is the ratio circumference - 2 times radius
<u><em>The area of the circle is equal to</em></u>

The number pi is the ratio Area - radius squared
Answer:
the fence needed to enclose the garden = 140 ft.
Step-by-step explanation:
given:
rectangular garden is 25 ft. by 45 ft.
find:
how many feet of fence are needed to enclose it?
use the perimeter of a rectangle formula = 2L + 2W
let L = 45 ft.
let W = 25 ft.
plugin values into the formula
P = 2L + 2W
P = 2(45) + 2(25)
P = 90 + 50
P = 140 ft.
therefore,
the fence needed to enclose the garden = 140 ft.
