To find the area of a circle, you can use the formula A = πr², where "A" is the area and "r" is the radius. So, for a circle with a radius of 5 inches, the area would be A = π(5)² = 25π. Approximating π as 3.14, you get about 78.5 square inches! So, the correct choice is D. Fun fact: The circle is a shape that has fascinated mathematicians and artists for centuries! From ancient Greek architecture to modern art, the perfect symmetry and beauty of circles make them a popular choice. Remember, as much as we love circles, they also represent plenty of math challenges, like those pesky pi approximations!
