Final answer:
The circumference of a circular swimming pool with a diameter of 6 ½ feet is 11 feet.
Step-by-step explanation:
To find the circumference of a circular swimming pool, you need to use the formula C = πd, where C represents the circumference and d represents the diameter. In this case, the given diameter is 6 ½ feet. Since the diameter is given in feet, the circumference will also be in feet.
First, we can convert the diameter to a decimal by dividing 6 by 2, which gives us 3. Then we add the ½, which is equal to 0.5. So the diameter is 3 + 0.5 = 3.5 feet.
Next, we can substitute the diameter into the circumference formula: C = πd = (22/7) * 3.5 = 11 feet.
