To me, "one-inch-circle" sounds like one inch IS the diameter.
It is because your 1 inch is one circle 1 inch one circle one of each get it.
A 6 inch circle is the measurement from one edge through the centre to the opposite edge. This line is known as the circle's diameter.
In a circle, Area = pi times radius squared: A = (pi)(r^2) Since the diameter equals 2 inches, the radius is one inch: A = (pi)(1^2) A = pi = 3.14 inches squared
one inch is one inch; one inch dia refers to one inch diameter of a circle; it is still one inch
A US 25 cent piece, a quarter, is close to one inch in diameter; it is just short. Its diameter is just about 15/16 of an inch. The diameter of a circle is the length all the way across the face of the circle going straight through the center. So a quarter gives you a good estimate of a circle with one inch diameter. Just imagine a circle very slightly bigger across.If you take an ordinary lead pencil and trace a circle using a US quarter as your template, you'll probably come even closer to a one inch diameter circle. Test it out with a ruler handy so you can get a better sense of it.

An insect bite could cause?æ one inch diameter red circle that has raised edges. It could be from a spider.
the diameter of a circle is defined by the largest length from one side of the circle to the other side of the circle. the area of a circle is equal to pi(3.14) times the radius squared. the radius is equal to half of the diameter.
If "3 inches" refers to the circle's diameter, then the radius is one-half of that.
If 13 inch refers to the diameter, then the radius is one-half that amount.
Area of a circle = pi*radius2
