The diameter of a circle is twice its radius, or 2r.
The formula for the circumference of a circle is the same, whatever its diameter. Circumference = pi*diameter.
pi*diameter = circumference Rearrange the formula so as the diameter is the subject of the formula: diameter = circumference/pi diameter = 7/pi = 2.228169203
The formula for the area of a circle is pi x radius2. The radius is half the diameter, and the diameter of an inscribed circle is the same as the length of a side of the square.The formula for the area of a circle is pi x radius2. The radius is half the diameter, and the diameter of an inscribed circle is the same as the length of a side of the square.The formula for the area of a circle is pi x radius2. The radius is half the diameter, and the diameter of an inscribed circle is the same as the length of a side of the square.The formula for the area of a circle is pi x radius2. The radius is half the diameter, and the diameter of an inscribed circle is the same as the length of a side of the square.
The circumference of a circle with a diameter of 18 inches is 56.5 inches.
If you are given the radius of the circle, you can use the formula: diameter = 2*radius If you are given the circumference of the circle, you can use the formula: diameter = circumference/pi
The diameter of a circle is twice its radius, or 2r.
The formula for the circumference of a circle is the same, whatever its diameter. Circumference = pi*diameter.
The formula to calculate the outside diameter of a circle is: outside diameter = diameter + (2 * thickness). This formula takes into account the thickness of the circle's material when calculating the overall dimension.
pi*diameter = circumference Rearrange the formula so as the diameter is the subject of the formula: diameter = circumference/pi diameter = 7/pi = 2.228169203
Formula: diameter = pi / circumference

The circumference of a circle with a diameter of 18 inches is 56.5 inches.
The formula for the circumference of a circle is pi * diameter or (2 radius.)
To calculate this you will need the diameter of the circle. The formula is: diameter/2*pi If you don't know the diameter you can also use the area of the circle: Sqrt(Area/pi) = radius
PI times the DIAMETER
A(Circle)=Pi*Diameter^2 ^2 = squared or to the 2nd power
