It is 20.69 inches, approx.
The circumference of a circle is calculated using the formula C = π*d, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. In this case, the diameter is 84 inches. Plugging this into the formula, we get C = 3.14159 * 84 = 263.89356 inches. Therefore, the circumference of a circle with an 84-inch diameter is approximately 263.89 inches.
