To find out how much trim is needed to surround the garden, we'll need to calculate the circumference of the circular garden. The circumference of a circle is the distance around the circle, and it can be found using the formula:
C = πd
where
C is the circumference,
π (pi) is a constant approximately equal to 3.14159, and
d is the diameter of the circle.
Given that the diameter of the garden is 12 feet, we can plug this value into the formula.
C = π * 12'
Now, we use the value of π, which is approximately 3.14159, to find the circumference:
C ≈ 3.14159 * 12
When we multiply 3.14159 by 12, we get approximately 37.69908 feet. However, because we want the amount of trim needed only "about" to the nearest foot, we should round this number to the nearest whole number. When we round 37.69908 to the nearest whole number, we get:
C ≈ 38'
Therefore, about 38 feet of trim is needed to surround the garden. Looking at the answer choices:
A) 432'
B) 48'
C) 144'
D) 38'
The correct answer is D) 38'.
