It is the equivalent of 1.66 centimeters which is just over 1/2 an inch
Any number you like. You can have a tiny circle with a tiny diameter or a huge big circle with a big diameter. The diameter is simply the "width" of the circle. It is the length of the line from one side to the other which passes through the centre.
Bottle caps are about 2 cm in diameter.
The radius of a circle is from the middle to the edge, or half the diameter. The circumference is like the perimeter of the circle, and the formula is pi times the diameter.
It looks like an extra large pizza which has a diameter of 18 inches
The circumference of a circle is 2*Pi*Radius or Pi*Diameter.

Pretty small. probably like a milimeter or half of a milimeter. but what do i know? i m only 6. Pretty small. probably like a milimeter or half of a milimeter. but what do i know? i m only 6.
To me, "one-inch-circle" sounds like one inch IS the diameter.

In order to find the diameter of a circle if you have the area is to rearrange the formula for the area of a circle to put diameter as the unknown, like so: PIE*d = Area of a Circle d = (Area of a Circle) / PIE Therefore if the area of your circle is 40cm, 40/PIE = 12.73cm and that's the diameter.
If you double the circumference. the diameter like wise would double.
A cylinder which the length of the tube is equal to to diameter of the circle.
12 x 12 sounds like a square, not like a circle. To specify a circle, you need a single number, for example the radius or the diameter. Assuming the diameter is 12, the radius would be half of that (6 units). The "size" of the circle can be considered this radius (6), the diameter (12), or the area calculated by the formula pi * radius * radius.
Not necessarily. If it is a semicircle - a circle bounded by an arc and the diameter of the original circle, it has two vertices - at the end of the diameter. However, a half circle need not have a side that is a straight line. It can be like the yin-yang symbol (see link). The half circle here has no vertex.
Pi is the ratio between the circumference of a circle and its diameter. The Sun is also round - like a circle.
