There are several countries in which the minor currency unit is a penny - including the US where a cent is called a penny!The UK penny has a diameter of 20.3 mm.
First of all, you have to promise us that you're talking about a circle.We're going to assume that, since you mentioned 'radius'.The perimeter of a circle ... usually called its 'circumference' ... is (pi) x (the circle's diameter).The circle's diameter is (2) x (its radius).Diameter = 200 millimetersCircumference = (pi) x (200) = 628.319 millimeters (rounded)
Usually centimeters...the smaller ones are millimeters. To judge, there are 2.54 centimeters in an inch.
Molecules, and atoms that make up molecules. An atom is made of smaller particles called protons, electrons, and neutrons. Smaller to this are groups such as fermions, Hadrons, Bosons
The diameter is the length across the middle of a circle. Half of the diameter is called the radius.
The smallest size of tephra is called ash. Ash particles are less than 2 mm in diameter.
The smallest size of sediment particle is called clay. Clay particles are smaller than 0.002 mm in diameter.
In a way they do, but even smaller "particles" are called atoms.
The largest diameter airways are the mainstem bronchi. Smaller-diameter airways are the bronchioles.

All of these changes break rocks into smaller pieces called rock particles
These ice particles are called hailstones, and they form within strong thunderstorms due to the upward and downward motion of air currents. The size of hailstones can vary depending on the strength of the storm and the amount of water vapor present in the atmosphere.
No. Ash consists of sand sized particles and smaller. Pebble sized particles are called lapilli.
They are called Enzymes
Yes, atoms can be divided into smaller particles called subatomic particles, which include protons, neutrons, and electrons. These subatomic particles are the building blocks of atoms and cannot be further divided into smaller particles in traditional chemical reactions.
Atoms are composed of subatomic particles like electrons, protons, and neutrons. However, there are even smaller particles called quarks, which are considered to be the fundamental building blocks of protons and neutrons. So, atoms are not the smallest particles.
It's smaller in diameter.
