How do you find the curcumference of a circle if you have the radius?
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
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 circumference of a circle inscribed in a rhombus?
To find the circumference of a circle in rhombus you eat SH*t .
How do you find the are of a circle?
(A=πr
How do you find out the radius of a circle?
The radius of a circle is half its diameter (the measure of the circle from one side across to the other).
If the diameter of the circle is 5m then what would the curcumference of the circle be?
15.70 meters Circumference = diameter x pi 5 meters x 3.14 15.70 meters
How do you find the curcumference of a circle if you have the radius?
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
How do you find the curcumference of a circle when you have the area?
a = πr2 ∴ r = √(a / π) c = 2πr ∴ c = 2π√(a / π) ∴ c = 2√π2 √(a/π) ∴ c = 2√(π2a/π) ∴ c = 2√(πa)
What is the curcumference of a circle with a 16 meter radius?
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
What is the radius if the curcumference is 23 inches?
Assuming we are talking about a circle... C = 2xpixr 23 = 2 x pi x r r = 23/(2xpi)
A circle has a curcumference that measures 18pi inches. What is the radius in inches of the circle?
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.
Who discovered the earths curcumference?
Eratosthenes was the first to measure the Earth's circumference pretty acurately.
What is a chord of a circle?
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.
What is curcumference of the mooon?
Moon's circumference is 6790 Miles. or 10,864 Kms. (i.e. 27% of the earth)
The area of circle if its curcumference is 14?
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
How do you find the chord of a circle?
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.
Which hemisphere does one find the Antarctic Circle?
You can find the Antarctic Circle in the Southern Hemisphere.
