r=d/2 c=Pi*d 2*r=d c=Pi*2*r where c is the circumference r is the radius and d is the diameter
Divide the known circumference by pi to find the diameter of the circle.
To find the circumference of a circle in rhombus you eat SH*t .
(A=πr
The radius of a circle is half its diameter (the measure of the circle from one side across to the other).
15.70 meters Circumference = diameter x pi 5 meters x 3.14 15.70 meters
r=d/2 c=Pi*d 2*r=d c=Pi*2*r where c is the circumference r is the radius and d is the diameter
a = πr2 ∴ r = √(a / π) c = 2πr ∴ c = 2π√(a / π) ∴ c = 2√π2 √(a/π) ∴ c = 2√(π2a/π) ∴ c = 2√(πa)
Well first you find on your calculator you need to find pi which looks something like this π. Now to find the curcumference of any circle the formula is pi multiplied by the diameter. The radius is 16 metres, and the diameter of any circle in life is two multiplied by the radius. So you do π times by 32 which equals 100.53(I rounded it off to the nearest 2 decimal places). or even easier 3.14 x radius 2 l l l PI times raduis 2 and now for area 2 times 3.14 times raduis
Assuming we are talking about a circle... C = 2xpixr 23 = 2 x pi x r r = 23/(2xpi)
Circumference equals 2 X pi X radius, so work backwards. 18pi=2 X pi X radius divide pi. 18= 2 X radius divide by 2. radius= 9.
A chord of a circle is a line segment drawn from any point on the curcumference of the circle to any other point on the circumference of the circle. The chord may pass through the center of the circle, in which case it is the diameter of the circle. The length of the chord will less than or equal to the diameter of the circle but greater than zero. If you draw a circle and start drawing chords, you'll quickly discover that there are an infinite number of unique chords that can be drawn in that circle. A link can be found below, and you can gather more information with the "click" of your mouse.
Moon's circumference is 6790 Miles. or 10,864 Kms. (i.e. 27% of the earth)
formula for circumference is : C= pie (times) diameter 14= pie Diameter 14=3.14 diameter so divide by pie on both sides to find the diameter aprox: 4.456 = diameter formula for area is : a= pie radius ^2 so find the radius which is half the diameter 4.456/2 =2.228 = radius square the radius 2.228^2= 4.964 times by pie area= 15.597
all you have to do is find a line with two endpoints on the circle also a diameter is the longest chord on a circle that runs through the middle of the circle.
You can find the Antarctic Circle in the Southern Hemisphere.
Find the area of the circle and divide by 4.
