What is the formula for the area of a circle with a diameter?
The general formula for the area of a circle is pi times the radius squared. The radius is half the diameter, so the area is pi times half the diameter times half the diameter again.
What is the formula to find the area of a circle with the diameter in it?
Area = Pi(d/2)2 where d = diameter
What is the area of a circle with a diameter of 3 in?
Use the formula area = pi x radius2. The radius is half the diameter.
How do you figure the area of a circle if you know the diameter?
The formula for the area of a circle is: area = pi x radius2. The radius is half the diameter.
How do you work out the area of a circle in a 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.

What is the formula to find the area of a circle with the diameter in it?
Area = Pi(d/2)2 where d = diameter
What is the formula for finding the diameter with the area?
If Area of a circle = (2)(pi)(r), and diameter = 2r, then: diameter = 2r = Area of circle / pi, where pi = 3.14
What is the area of a circle with a diameter of 3 in?
Use the formula area = pi x radius2. The radius is half the diameter.
How do you figure the area of a circle if you know the diameter?
The formula for the area of a circle is: area = pi x radius2. The radius is half the diameter.
What is the mathematical formula for finding the radius of a circle?
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
What is the area of a circle that has a diameter of 34 ft?
Divide the diameter by 2 to get the radius. Then use the standard formula for the area of a circle.

How do you find the area circumfrance and the diameter of a circle?
Formula for area: A = Pi*R² (Pi = 3,1416 and R² is the radius multiplied by itself) Formula for circumference: C + Pi*D (D is diameter) Formula for Diameter: D = 2*R (radius multiplied by 2))
What is the formula to find the diameter of a circle when the area is known?
If: pi*radius2 = area Then: radius = square root of (area/pi) And: diameter = 2*radius
What is the formula for finding diameter when given the area?
Assuming you mean a circle, use the formula for the area of a circle, which is usually expressed in terms of the radius, and solve for the radius. Then you can multiply that by two to get the diameter, since the diameter is twice the radius.
What is the formula to be used if the diameter is given?
The answer depends on the formula for what: the radius, circumference, length of an arc, area, area of sector, area of segment: each one has a different formula.
