What is the circumference of a circular swimming pool with a diameter of 6 ½ feet? ______________ ft.
To calculate the circumference of a circle, you use the formula: C = π * d, where C is the circumference and d is the diameter.
In this case, the diameter of the swimming pool is given as 6 ½ feet. To use this value in the formula, you need to convert it to decimal form.
6 ½ feet = 6.5 feet
Now, you can substitute the values into the formula:
C = π * d
C = π * 6.5
Using an approximate value of π = 3.14, you can calculate the circumference:
C = 3.14 * 6.5
C ≈ 20.41
Therefore, the circumference of the circular swimming pool is approximately 20.41 feet.
