Answer: Option D

Explanation:

To find the size of the pizza box that would best fit the small pizza, we can use the diameter of the pizza as the size of the pizza box.

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 area of the small pizza is 78.5 square inches. We can use this information to find the radius of the pizza:

78.5 = πr^2

Now, solve for "r":

r^2 = 78.5 / π r^2 ≈ 25 r ≈ √25 r ≈ 5 inches

So, the radius of the small pizza is approximately 5 inches. To find the diameter (which is also the size of the pizza box needed), simply double the radius:

Diameter = 2 * 5 inches = 10 inches

Therefore, a 10-inch pizza box would best fit the small pizza.
