Air pressure inside a hurricane

[BeiW]

Homework Statement

Estimate the air pressure inside a category 5 hurricane, where the wind speed is 300 km/hr.

Homework Equations

P=F/A

The Attempt at a Solution

I converted km/hr to m/s.
V=83.33m/s.
That's all I can get. I don't know the area of a category 5 hurricane or the force of one.
Is there any other equation I can use?
