Explain your answer and how you found it in a complete sentence.

Answer 1

Scott needs to buy 50.24 feet of fencing

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:

$C = \pi d$

Where, "d" is the circumference of circle

From given,

d = 16 feet

Therefore,

$C = 3.14 \times 16\\\\C = 50.24$

Thus, Scott needs to buy 50.24 feet of fencing
