Area of a circle = pi*radius2
Assuming a circle with a diameter of one half inch, A = 2Ï€r so the area in square inches would be half of pi or about 1.57 in2.
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.
A circle is defined by only one measure. You cannot have a 30 inch by 60 inch circle!A circle is defined by only one measure.

Use the formula c=d(pi)
It is because your 1 inch is one circle 1 inch one circle one of each get it.
Area = pi * diameter * diameter /4 = 3.14 * 1 *1 /4 = approx = 3/4 of square inch
To me, "one-inch-circle" sounds like one inch IS the diameter.
No, one-half inch drywall is not actually one-half inch thick. It is typically around 0.48 inches thick.
When you say "a 20 inch circle", I'm going to assume you mean the distanceall the way across it, through the center ... that is, the circle's "diameter".The area of a circle is (pi) x (Radius)2 = (pi) x (100) = 314.159 square inches (rounded)
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.
