The radius is half of the diameter. So, if the radius is 7 the diameter is 14.
It is the equivalent of 1.66 centimeters which is just over 1/2 an inch
Area = pi*r2A ratio.A = pi*(12)2-------------A = pi*(10)2cancel all like factors144/100= 1.44 times larger==============
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.
To me, "one-inch-circle" sounds like one inch IS the diameter.
The diameter of a circle is the distance across the circle passing through its center. To find the diameter of a circle, you can simply double the length of the radius. If the circle has a radius of 24 inches, then the diameter would be 48 inches. So, the diameter of a 48-inch circle is also 48 inches.
The radius is half of the diameter. So, if the radius is 7 the diameter is 14.
Oh, dude, the diameter of a circle is just the distance across the circle passing through the center. So, if you have a 30-inch circle, the diameter would be 30 inches. It's like the circle's belly button - right in the middle, measuring from one side to the other.

Black, hard rubber, perfect circle with a diameter of about 3 inches and a height of about 1 inch.

Oh, dude, this is like basic math 101. The diameter of a circle is just twice the radius, so if the radius is 1 meter, the diameter is 2 meters. It's like the circle's way of saying, "I'm just twice as big as my radius, no big deal."
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.
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.
