Solution:
Given that,
Scott wants to buy fencing to place around a circular rock garden
The diameter of the circle is 16 feet
The amount of fencing Scott will need to buy is equal to the circumference of circular garden
The circumference of circle is given as:
[tex]C = \pi d[/tex]
Where, "d" is the circumference of circle
From given,
d = 16 feet
Therefore,
[tex]C = 3.14 \times 16\\\\C = 50.24[/tex]
Thus, Scott needs to buy 50.24 feet of fencing
