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 formula for finding the area of a circle when you know the diameter?
D=Diameter, pi=3.14159... Area of circle = (D/2)2 * pi
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 formula for finding the radius?
The formula for finding the radius of a circle is circumference divided by double of pi. If area is given instead of circumference, the radius may be found by dividing the area by pi, then finding the square root of the resultant quotient. It is also equal to half of the diameter, or the diameter divided by 2.
What is the formula for finding circumference and area of a circle?
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
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 for finding the diameter when you only have the area?
If Area of a circle = 2 * pi * rAnd Diameter = 2 * rTherefore:Diameter = 2 * r= Area of circle / piwhere pi = 3.14
What is the area of a circle if it has a diameter of 16 inches?
Formula for finding the area of a circle: Area = pi * r2 a = 3.14 * 82 a = 3.14 * 64 a = 201.06
Is the formula for finding the area of an oval the same as the formula for finding the area of a circle?
No because the formula for finding the area of an oval, which is an ellipse, is quite different
What is the formula in finding the height of a cylinder?
The answer depends on what information you are given: volume and radius or diameter, or surface area and radius, etc.
How do you find a diameter of a circle?
If you have the circumference: circumference = (pi) * diameter diameter = circumference / (pi) If you have the area: area = (pi) * radius * radius radius = square_root(area / pi) radius = diameter / 2 diameter = 2 * square_root(area / pi)
What is the formula for finding the area of an ellipse?
the formula for finding the area of an ellipse is add it then multiply and subtract that is the final
