In order to do this, you must have the radius in feet.-- Square the radius (multiply it by itself)-- Multiply the answer by 'pi'. (3.142 is close enough)-- The answer is the area of the circle, in square feet.
This is the area of a circle with a radius of 100 miles →area = π × radius² = π × (100 miles)² = 10,000π sq miles ≈ 31416 sq miles
