Area of Circle = r r=radius 5 feet 3 What is
The diameter of the table is 5 feet, so the radius is 5/2 = 2.5 feet. The area of a circle is πr², where r is the radius. Therefore, the area is π(2.5)² = 6.25π square feet. Using π ≈ 3.14, the approximate area is 6.25 * 3.14 ≈ 19.625 square feet. Of the given options, 25 square feet is the closest approximation.
其他选项分析：A：16 square feet is too small; it would be the area if the radius were approximately 2.26 feet.
B：20 square feet is close, but not as close as 25 square feet.
D：79 square feet is far too large; it would be the area if the radius were approximately 5 feet.
