Question
At a campground, a rectangular fire pit is 5 feet by 4 feet. What is the area of the largest circular fire that can be made in this fire pit? Use 3.14 for π. Round to the nearest square inch.

Diameter = 4'
radius = 2' = 24 inches
Area = pi r^2 = 576 pi in^2
radius = 2' = 24 inches
Area = pi r^2 = 576 pi in^2

clearly the largest circle will have a diameter of 4 ft, or a radius of 2 ft
area = π(2^2) = 4π ft^2 = ......
In this time of calculators, using 3.14 for π and then rounding off that rounded constant is rather silly. Most calculators have a special key for π, use it.

The circle is inscribed within the the rectangle and so it has diameter equal to the smaller of the two sides of the rectangle.
r=1.5 ft=18 in
Area=pi*r^2=324pi in^2 or approx 1017 square inches
