The total area of the two bases can be calculated by finding the area of one base and then multiplying it by 2.
The area of a circle is given by the formula A = πr^2, where r is the radius of the circle. Since the diameter is 5 inches, the radius is half of that, which is 5/2 = 2.5 inches.
Plugging the radius into the formula: A = 3.14 * (2.5)^2 = 19.625 square inches.
Multiplying this by 2 to get the total area of both bases: 19.625 * 2 = 39.25 square inches.
Therefore, the total area of the two bases is 39.25 square inches. So the correct answer is:
39.25 square inches
