Use the area formula for a circle. A = pi r squared. r is the radius, so solve for r and multiply by two to find the diameter. Need more help? Substitute the area for A, and 3.14 for pi in the previous equation. So to find the diameter, Divide area by 3.14 then find the square root of that and multiply by two.
- So Diameter = 2*Square_root(Area/pi)

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 formula to find diameter of circle when area is known?
(Pi)r^2=area & 2r=d
Square foot of a circle?
To find the area of a circle, either the diameter or the circumference must be known. The formula for the area from the diameter is (pi)*(1/2 of diameter) squared. From the circumference, simply substitute (circumference / pi) for diameter.
How to find the area of a circle?
Circumference= 3.14 x Diameter Area of circle= 3.14 x diameter x diameter
How do you find the area of a semi-circle if you know the diameter?
A semicircle is 1/2 of a circle. Find the area with the diameter you are given as if you had a whole circle, then divide that answer by 2 to get the area of the semicircle.

How do I figure the area of a circle by diameter?
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
How to find the area of a circle?
Circumference= 3.14 x Diameter Area of circle= 3.14 x diameter x diameter
How do you find the area of a semi-circle if you know the diameter?
A semicircle is 1/2 of a circle. Find the area with the diameter you are given as if you had a whole circle, then divide that answer by 2 to get the area of the semicircle.
How do you find the diameter of a circle if you know the circumference?
Divide the known circumference by pi to find the diameter of the circle.
How do you find the diamter of a circle if you know the area?
In order to find the diameter of a circle if you have the area is to rearrange the formula for the area of a circle to put diameter as the unknown, like so: PIE*d = Area of a Circle d = (Area of a Circle) / PIE Therefore if the area of your circle is 40cm, 40/PIE = 12.73cm and that's the diameter.
Find the area of a circle with a diameter of 6?
The area of a circle with a diameter of 6 units is: 28.27 square units.
How do you find diameter of a circle with the area of 58.69?
Diameter is 8.64444

How do you find the cicumference of a circle whichout knowing its area radius or diameter?
Given is a circle. Not known is its area A. Not known is its radius r. Not known is its diameter d. You want to calculate its circumference C. Impossible. It cannot be calculated. The only other way is to measure it with a tape measure.
