Final answer:
The circumference of a circle with a diameter of 16 ft is approximately 50.26544 ft, using the formula C = π × d.
Step-by-step explanation:
The circumference of a circle is calculated using the formula C = π × d, where C is the circumference and d is the diameter of the circle. In this case, the diameter is given as 16 ft. Therefore, to find the circumference, we multiply 16 ft by π (approximately 3.14159).
C = π × 16 ft
C ≈ 3.14159 × 16 ft
C ≈ 50.26544 ft
So, the circumference of a circle with a diameter of 16 ft is approximately 50.26544 ft.
