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


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.


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.

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

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 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.


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.
