Find the circumference of a circular swimming pool with a diameter of 22 feet. Use 3.14 as an approximation for [tex]\(\pi\)[/tex]. Round your answer to the nearest whole foot. Enter only the number.

The solution is:



Answer :

To find the circumference of a circular swimming pool with a given diameter, follow these steps:

1. Identify the given values:
- Diameter ([tex]\(d\)[/tex]) of the pool is 22 feet.
- We'll use [tex]\(3.14\)[/tex] as an approximation for [tex]\(\pi\)[/tex].

2. Recall the formula for circumference:
The formula to calculate the circumference ([tex]\(C\)[/tex]) of a circle is:
[tex]\[ C = \pi \times d \][/tex]

3. Substitute the given values into the formula:
[tex]\[ C = 3.14 \times 22 \][/tex]

4. Perform the multiplication:
[tex]\[ C = 69.08 \text{ feet} \][/tex]

5. Round to the nearest whole number:
- The decimal part of 69.08 is 0.08, which is less than 0.5.
- Therefore, we round down.
[tex]\[ C \approx 69 \text{ feet} \][/tex]

So, the circumference of the circular swimming pool, rounded to the nearest whole foot, is 69 feet.
