If Area of a circle = 2 * pi * r
And Diameter = 2 * r
Therefore:
Diameter = 2 * r
= Area of circle / pi
where pi = 3.14
Yes, if it is a square the Area=A=l2 where l is the length and If you are given the area, then l=square root (A)
Depends on the information that you DO have. Half the diameter is the easiest formula, but that only works if you know the diameter.
Circumference = Pi * D (the diameter) Therefore D = Circumference / Pi Naturally all circles have a circumference, but if this value is known then we can find the diameter by dividing this value by Pi. (Note: Pi is a special number and we can only ever use an approximation to its value.)
There is only one formula for pi, which is the ratio of the circumference to the diameter of a circle.
The volume is proportional to the cube of the diameter, but the area, only to the square of the diameter. For example, if you double the diameter, the area will increase by a factor of 4, and the volume, by a factor of 8. Thus, the area/volume ratio will worsen, by a factor of 2.The volume is proportional to the cube of the diameter, but the area, only to the square of the diameter.

Circumference of a circle = (pi) x (diameter)
diamter=2xradius, so if you have the diameter, divide by 2 and you have the radius. r=d/2
There is no circumference of a cone, but, we only do the circumference of the circle. the formula for the circle is pi times D. D= Diameter

Given only the lateral area, you cannot determine the diameter.

pi*radius2 = area of a circle radius2 = area/pi radius = square root of (area/pi) diameter = 2*radius
The formula for finding the surface area of a rectangular prism is 2(wh + lw + lh), where w is width, h is height, and l is length. 3.14 is the value for pi, which is only used for circular objects, like circles, cylinders, and spheres. It has nothing to do with rectangular prisms. Click on the related link below for an illustration of the formula for the surface area of a rectangular prism.
By dividing the diameter by 2 will give the circle's radius. Area of any circle = pi*radius squared.
