Answer:
Explanation:
The area of a circle is given by the formula:
A = πr^2
where π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.
In this case, we are given the diameter of the circular glass window, which is 5 feet. The radius is half the diameter, so we can calculate it as:
r = d/2 = 5/2 = 2.5 feet
Using the formula for the area of a circle, we can find the approximate area of the circular glass window as:
A = πr^2
= 3.14 x (2.5)^2
= 3.14 x 6.25
= 19.625 square feet (rounded to three decimal places)
Therefore, the approximate area of the circular glass window is 19.625 square feet, using π ≈ 3.14.
