To find the circumference of a circle in terms of π, you can use the formula:C=π×d

where C is the circumference and d is the diameter.

In this case, the diameter of the circle is given as 9 feet. To find the circumference, substitute d=9 into the formula:

C=π×9

Now, multiply π by 9:

C=9π

So, the circumference of the circle is 9π feet. This expression represents the exact circumference in terms of π. If you want a numerical approximation, you can use the value of π (approximately 3.14) and calculate 9×3.149×3.14.

In conclusion, the circumference of the circle with a diameter of 9 feet is 9π feet or approximately 28.2628.26 feet when using the numerical approximation for π.
