Yes, it is.
According to the World Pool-Billiard Association, a pool ball is 2.25 inches in diameter, and has a tolerance of +/- 0.005 inches. In other words, it must have no pits or bumps more than 0.005 inches in height. That's pretty smooth. The ratio of the size of an allowable bump to the size of the ball is 0.005/2.25 = about 0.002. The Earth has a diameter of about 12,735 kilometers (on average, see below for more on this). Using the smoothness ratio from above, the Earth would be an acceptable pool ball if it had no bumps (mountains) or pits (trenches) more than 12,735 km x 0.00222 = about 28 km in size. The highest point on Earth is the top of Mt. Everest, at 8.85 km. The deepest point on Earth is the Marianas Trench, at about 11 km deep. Hey, those are within the tolerances! So for once, an urban legend is correct. If you shrank the Earth down to the size of a billiard ball, it would be smoother.

What does the black 8 ball say in billiard pool?
The black 8 ball during a billiard pool game told the teenage players, "See, being called on last to be on the team is sometimes the best outcome because you win!The black 8 ball during a billiard pool game proudly yelled, as he slid into the pocket that the player correctly called, "I've rolled longer than the stripes and solids to get here."The black 8 ball during a billiard pool game said, "Having a number painted on your belly sure makes people avoid you...that is, until one player finally calls your name!"
Why does a red ball weigh more than a blue ball?
Earth's gravitational pull on the red ball is greater than on the blue ball.
Can you give me a sentence using the word smoother?
A smoothie is smoother than a malt.
Is Earth the same size as a soccer ball?
No, Earth is bigger than a soccer ball. The analogy you may have seen is that if Earth were the size of a soccer ball, the Moon would be the size of a tennis ball, and would orbit the Earth at an average distance of 22 feet away.
Will a billiard ball turn into ashes if it gains the speed of light?
We know from the past 110 years of Physics that it's not possible for a billiard ball to accelerate to the speed of light. We also know from the same physics that if the ball were traveling at the speed of light, its mass would be infinite, and its thickness in the direction of its motion would be zero. There's no hint of any reason whatsoever that it should turn to ashes, or to any other substance, other than what it was last time it dropped into the side pocket.
Why it is smoother to ride a bicycle on a paved road than on a dirt road?
Because pavement is smoother.
Why does a ice-hockey puck have less friction than a ball rolling on the ground?
Ice has a much smoother surface than the surface of the ground, therefore there is less friction acting on the hockey puck compared to a ball rolling on the ground. Ice is nearly a frictionless surface.
What is the circumference of the Earth?
The equatorial circumference of the Earth is about 40,075 km (24,901 m).The polar circumference of the Earth is about 40,008 km (24,860 m).More Precisely:Earth is not a perfect sphere, but is "flattened" at the poles. Its shape is described as an oblate spheroid. So, the Earth's circumference is about 68 km (41 m), larger around its bellythan around its poles.This difference is small enough that, were the earth shrunk down to the size of a billiard ball, it would be more perfectly round than most billiard balls.Caveat: The numbers for circumference are always approximations because Earth's surface is irregular and constantly changing. The tidal bulging (constantly shifting) is a dynamic factor. Polar measurements vary with longitude. So these approximations can differ by a kilometer or two.
How does volcanic activity affect the formation of volcanic rock?
It depends where the rock was formed. If it was formed inside the earth, it would be rough. If it was formed on the surface, it would be smoother than the rock formed inside the earth.
Is a softball smoother than a baseball?
yes
How many more sides has a hexagon than a normal billiard table?
2
Why is the east coast smoother than the west coast?
It is smoother because the wind and waves are stronger on the west side.
