Its 26 cause radius is half of a diameter so u multiply 13 by 2
D = 2r

It depends on what measure the 72 refers to - radius or diameter.
Circumference of a circle = 2*pi*radius or pi*diameter
The surface of a circle is given by the formula d2pi/4, so for our 44 inch diameter table, that gives 484pi square inches, which is aproximately 1520.531 square inches.
Hi.. a 5 foot diameter table would have a 15 foot 8 and a half inch circumference.. or in metric it would be 4.788 meters. Paul.

It is its radius which is 72/2 = 36 inches
226.98 inches squared.
diameter = radius x 2 radius = 5ft / 2 = 2.5 ft you may try using the calculator linked below
If the table is 60 inches across, the diameter is 60 inches.
Circumference is found by the equation C = 2 * pi * r, where r is the radius and pi is the constant pi. We are given the diameter. If you look at a circle, the diameter of it is the distance from one end of the circle to the other. We want the radius of the circle. The radius is the distance from any point along the circle to the center of the circle. If we let the diameter = d and the radius = r, we can write a formula for the diameter in terms of the radius. Because the radius is half of the distance of the diameter, d = 2*r 15 = 2 * r (divide both sides by 2) r = 7.5 so C = 2*7.5*pi C = 15pi Note that we could have used C = pi*d, although this is not usually how circumference is expressed.

The amount of paint needed is a function of the radius
It depends on what measure the 72 refers to - radius or diameter.
You would need enough fabric to make a circular cloth ten feet in diameter (assuming you mean the tabletop is a circle eight feet in diameter - you aren't exactly clear on that - whether the tabletop is 8 feet in diameter or 8 feet in circumference).
