The area of Elena's circular table top, with a diameter of 28 inches, is approximately 615.44 square inches.

The area A of a circle can be calculated using the formula:


\[ A = (\pi)/(4) * D^2 \]

where D is the diameter of the circle.

Given that the diameter D of the circular table top is 28 inches, we can substitute this value into the formula:


\[ A = (\pi)/(4) * (28)^2 \]\[ A = (\pi)/(4) * 784 \]\[ A = 196\pi \]

So, the area of the circular table top is
\(196\pi\) square inches. If you prefer a numerical approximation, you can use 3.14 as an approximation for π:


\[ A \approx 196 * 3.14 \] A \approx 615.44 \]

Therefore, the approximate area of the circular table top is 615.44 square inches.
