Answer:

r = 2.14 miles

Explanation:

Area of a circle = πr²

Where,

π, pi = 3.14

r, radius = ?

Area = 14.4 square miles

Area of a circle = πr²

14.4 = 3.14 * r²

14.4 = 3.14r²

r² = 14.4/3.14

r² = 4.5859872611464

r = √4.5859872611464

r = 2.1414918307447

Approximately to the nearest hundredth of a mile

r = 2.14 miles
