The area of a circle, in terms of pie, with a diameter of 36 is: about 324pi
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.
the diameter is the length across the circle, the area is pie r squared r is radius, which is half of the diameter
Circumference of a circle = diameter*pi
A circle with a 7 inch diameter has an area of 38.48451.
Solve the equation for the area of the circle (area = pi x radius2) for radius. Multiply the radius by 2 to obtain the diameter.

36 pie
Circumference of a circle = diameter*pi
pie x 4.5 squared
A circle with a 7 inch diameter has an area of 38.48451.
perimeter of a circle = pie *r^2 Hence r^2 = perimeter/ pie hence r = (perimeter/Pie)^1/2 Hence diameter = 2r= 2* ( perimeter?pie) ^1/2

Alike: Their in the formula to find the area of the circle pie times radius squared or pie times diameter divided by 2 Different: In a circle, radius is half of the diameter. Example: If the diameter of a circle is 10. Then the radius would be 5.
Solve the equation for the area of the circle (area = pi x radius2) for radius. Multiply the radius by 2 to obtain the diameter.
The area of a circle is pie(22/7) or (3.14) times R2 R = the radius of the circle (1/2 of the diameter)
Using 3.14 as Pi the area of circle is: 28.259999999999998
