The area of circle is given by,
A = pi*(D^2)/4
where
D = diameter
Substituting,
A = ( 3.14 * (5/2)^2 )/4
A = 4.90625 ft^2
In mixed number, this is 4 29/32 ft^2.

In this case, we are given the diameter of the table top, which is 2 1/2 feet. The radius is half the diameter, so we need to divide the diameter by 2.
2 1/2 can be written as an improper fraction: 5/2.
Now, we can calculate the radius by dividing 5/2 by 2.
(5/2) ÷ 2 = 5/4 = 1 1/4
So, the radius of the table top is 1 1/4 feet.
Now, we can calculate the area of the table top using the formula A = πr^2.
Plugging in the values:
A = 3.14 × (1 1/4)^2
To square 1 1/4, we convert it to an improper fraction: 1 1/4 = 5/4
A = 3.14 × (5/4)^2
Simplifying, we square the fraction:
A = 3.14 × (25/16)
Now, we multiply the numerators:
A = (3.14 × 25) / 16
And then divide by the denominator:
A = 78.5 / 16
We can simplify this fraction by dividing the numerator and the denominator by their greatest common divisor, which is 2:
A = (78.5 ÷ 2) / (16 ÷ 2)
A = 39.25 / 8
Now, we can write the mixed number:
39.25 / 8 = 4 21/25
Therefore, the area of the table top is 4 21/25 square feet.
