the fraction 22/7 is often used as an approximation for the value of pi. it is off from the actual value by about 0.04 percent (1 in 2500).
This would be like measuring a football field and being off by about 1.5 inches on your measurement.
The fraction 355/113 is amazingly close, better than 1 part in 10 million
You can't write pi accurately as a fraction, but you can approximate it with 22/7.
22/7 (roughly). There is no fraction exactly equal to pi
pi/circumference = 1/(2*diameter).
In any circle, the product of pi and the diameter will be the circumference. That is because pi is the ratio of the diameter of a circle to its circumference. Here is the equation: c = pi x d
The formula for finding the radius of a circle is circumference divided by double of pi. If area is given instead of circumference, the radius may be found by dividing the area by pi, then finding the square root of the resultant quotient. It is also equal to half of the diameter, or the diameter divided by 2.
2 pi r times the circumference sqaured. then take this and find out its square root. This however, only works if you have the circumference. If you have both the volume and the height, you can find the formula for the radius by solving the following literal equation for "r": V=1/3 r^2(3.14)(H) r=(3V/pi H)square root
The equation would be the distance traveled divided by the time. So the radius of the Earth's orbit is about 93 million miles, and the formula to calculate the circumference of a circle is 2*pi*radius. The Earth's orbit is not a circle but an ellipse; however, the eccentricity (amount of difference between the ellipse and a perfect circle) is quite small. The time of the orbit is 356.24 days times 24 hours, or 8766 hours. (Rounded off, because I'm using round numbers for the radius and blowing off the eccentricity of the orbit). I'll round off the irrational number "pi" to 3.1412, because it would be irrational to use anything more precise, since the radius is approximate, too. So 584,263,200 miles / 8,766 hours = 66,650 miles per hour. Approximately.
We get 3432 miles for the radius, but that's no big deal. We'll work with 3429.5,and we're also going to round the period of rotation to 24 hours.Radius = 3429.5Circumference = (2 pi) x (radius) = 6,859 piSpeed = Circumference / time = 6,859 pi / 24 hours = 898 miles per hour (rounded)

2r(pi)=C where C is circumference. Therefore the radius equals C/2(pi)
The value of pi is found by dividing the circumference of a circle by its diameter and pi is an irrational number which means it can not be expressed as a fraction.
Pi is a number. You get pi when you divide the circumference of a circle by it's radius. 22/7=3.14 is the closest fraction.
The circumference of a circle is equal to the diameter times pi. The number pi CAN NOT be expressed exactly as a fraction, or as a decimal. Common approximations are 3.14 in decimal, or 22/7 as a fraction.
No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)
You can either 1)You can divide out the fraction used for pi then multiply by the diameter or 2)Put the diameter over 1 then multiply across with the fraction used for pi.
circumference=pi circumference=pi circumference=pi
The circumference is 2*pi*radius (not raduis) and this formula is applicable whether the radius is an integer, a fraction, or even an irrational number.
The circumference of a circle when divided by its diameter is the value of pi which is an irrational number that can't be expressed as an exact fraction.
The diameter of a circle can be divided into the circumference of a circle pi times. The number pi is about 3.14 in decimal form. Because pi is an irrational number, it cannot be written as a fraction of integers or as a terminal or repeating decimal. The circumference of a circle is said to be pi times the diameter, so by dividing the diameter into the circumference, we would get pi as a quotient.
It seems like there's an error in your question. Circumference (of a circle) = pi * diameter. You can approximate pi with the fraction 22/7, then Circumference = (22/7)*49 = 154
