There are 314 people in Geometrytown. The town is circular. The diameter is 10 miles. What is the population in people per square mile?

4 people/mi²

The diameter is 10 miles, so the radius is 5 miles. The area of the town is:

A = πr²

A = π (5 mi) ²

A ≈ 78.5 mi²

314 people / 78.5 mi² ≈ 4 people/mi²
