The area of a circle is calculated using the formula A = πr^2, where π is approximately 3.14 and r is the radius.
Given that the radius of the circle window is 1.5 feet, we can substitute this value into the formula:
A = 3.14 * (1.5)^2
A = 3.14 * 2.25
A = 7.065
Therefore, the area of the window is approximately 7.1 square feet (7.1).
