Answer:
So length of top of table is 3x-7 inches.
Step-by-step explanation:
Here we are given that the top of the table has a width that is given by 2x inches.
The area of the top is given by:

Now the top of the table is of the shape of rectangle and area of rectangle is given by:

where l is length of the table and w is width of the table.
Plugging the values of A and w in the formula we have:

Dividing by 2x,
l=3x-7 inches
So length of top of table is 3x-7 inches.
The diameter of a circle is calculated by using the formula D=r2pi so plug in the known values to find r=2/pi. Next plug r into the area of a circle formula(A=r^2pi) do so and get 4/pi
