How much fencing is needed to enclose a circular pond with diameter 12.5 feet?
A.
37.5 feet
B.
19.625 feet
C.
78.5 feet
D.
39.25 feet****
Would it be 12.5 / pi?
Every time I try it, the answer ends up being 3.980
nevermind, I got it. I keep asking way to much questions lol. This will be my last one for today haha.
the harder you work the easier it will be
To find the amount of fencing needed to enclose a circular pond, you need to calculate the perimeter of the pond. The perimeter of a circle is found by multiplying the diameter by π (pi), which is approximately 3.14159.
In this case, the diameter of the pond is given as 12.5 feet. Therefore, the radius of the pond is half the diameter, which is 12.5/2 = 6.25 feet.
The perimeter of the circular pond is the circumference of the circle, which is given by the formula:
C = 2πr
Substituting the value of r as 6.25 feet, we can calculate:
C = 2 * 3.14159 * 6.25
C ≈ 39.25 feet
Therefore, the correct answer is option D. 39.25 feet.
