"<em>The distance around a circle"</em> = Circumference
Circumference = 3.14 * diameter
3900 * 3.14 = 12246
The circumference (distance around the crater) is equal to 12,246 feet

This is an incomplete question, here is a complete question.
A hurricane wind blows across a 7.00 m × 12.0 m flat roof at a speed of 150 km/h.
What is the pressure difference Δp = p(inside)-p(outside)? Use 1.28 kg/m³ for the density of air. Treat the air as an ideal fluid obeying Bernoulli's equation.
Answer : The pressure difference will be, 
Step-by-step explanation :
As we are given:
Speed = 150 km/h = 41.66 m/s
Density = 
Area = A = 7.00 m × 12.0 m
Formula used :

Now put all the given values in this formula, we get:


Thus, the pressure difference will be,
