The circumference of a circle is calculated using the formula C = 2πr, where r is the radius of the circle. In this case, the radius is half of the diameter, so it would be 15 feet. Plugging this into the formula, we get C = 2π(15) = 30π feet. This is approximately 94.25 feet around a 30-foot circle.
