Answer:
The cross section parallel to the base of a cylinder is a circle. The area of a circle is given by the formula:
A = πr^2
where A is the area and r is the radius.
In this case, the radius of the circle is 4 inches, so we have:
A = π(4)^2
A = 16π
Using 3.14 for π, we can simplify:
A = 16(3.14)
A = 50.24
Therefore, the area of the cross section parallel to the base of the cylinder is 50.24 square inches.
