What is the circumference of the pool?
Understand the Problem
The question is asking for the circumference of a circular pool based on its diameter of 12 feet. To find the circumference, we will use the formula C = π * d, where d is the diameter.
Answer
The circumference of the pool is approximately $37.68$ feet.
Answer for screen readers
The circumference of the pool is approximately $37.68$ feet.
Steps to Solve
-
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. -
Substitute the given diameter
We know from the problem that the diameter $d$ of the circular pool is 12 feet.
Now, substitute $d$ into the formula:
$$ C = \pi \times 12 $$ -
Calculate the circumference
Using the approximate value of $\pi \approx 3.14$, we can calculate:
$$ C \approx 3.14 \times 12 $$
Now, perform the multiplication:
$$ C \approx 37.68 $$ -
Final answer
Therefore, the circumference of the pool is approximately 37.68 feet.
The circumference of the pool is approximately $37.68$ feet.
More Information
The circumference is a measure of the distance around a circle. In practical terms, knowing the circumference can help in various situations, like determining how much material is needed to cover the pool's edge.
Tips
- Forgetting to use the value of π: Students sometimes skip the multiplication by $\pi$ when calculating the circumference.
- Using the radius instead of diameter: Ensure you're using the diameter in the formula, not the radius.
