Final answer:
The circumference of a circle with a diameter of 70 inches is approximately 219.8 inches.
Step-by-step explanation:
The formula to find the circumference of a circle is C = π × D, where C is the circumference and D is the diameter. In this case, the diameter of the circle is given as 70 inches. So, we can substitute this value into the formula:
C = π × 70
To get the circumference, we can use the approximation of π as 3.14:
C ≈ 3.14 × 70 = 219.8 inches
Therefore, the circumference of the circle is approximately 219.8 inches.
