$4,069.44 \mathrm{~m}$
Solution
Solution Steps
To find the circumference of a circle, we use the formula \( C = \pi \times d \), where \( d \) is the diameter of the circle. Given the diameter is 36 meters and using \(\pi = 3.14\), we can calculate the circumference and round it to the nearest hundredth.
Step 1: Identify the Formula for Circumference
To find the circumference of a circle, we use the formula:
\[ C = \pi \times d \]
where \( C \) is the circumference and \( d \) is the diameter.
Step 2: Substitute the Given Values
Given:
\[ \pi = 3.14 \]
\[ d = 36 \, \text{m} \]
Substitute these values into the formula:
\[ C = 3.14 \times 36 \]
Step 3: Perform the Calculation
Calculate the circumference:
\[ C = 113.04 \, \text{m} \]
Step 4: Round to the Nearest Hundredth
The calculated circumference is already rounded to the nearest hundredth:
\[ C = 113.04 \, \text{m} \]
