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.

To find the diameter of a circle when given the circumference, you can use the formula: circumference = π * diameter. Given a circumference of 84 units, you can plug this value into the formula and solve for the diameter. Dividing 84 by π gives you approximately 26.67 units as the diameter of the circle.
Circumference equals pi times diameter; so C = 84*pi or about 263.9.
