2 pi r
The circumference of a circle is (pi) x (diameter), or (2 pi) x (radius).
4.172(pi) metersThe formula for the circumference of a circle is 2r(pi) where r is the radius.
Circumference.
Pi is always defined as the constant that represents the circumpherence of a circle divided by that circle's diameter. It is approximately: 3.141592653589.
do you mean the equation for a diameter of a circle over its circumpherence as in pi? Pi is a never ending number but ir is most commonly recognisizedmby its first 5 nmbers 3.1415
actually its really hard and scientist know how but they still dont know the answer but i can still tell you how to do it first you need to draw a perfect octagon after that you draw tiny little bity squares inside it all being the same size not a tad off then find how many square milimeters one of them has and times that by how many squares you drew you then you draw that ammount of those size of squares of the answer then you draw a circle around that and you find the circumpherence of that circle and time that circumpherence by 3.14 i know what you are think why would we do that when we did it for the circle all ready but you have to do it again for the octagon
There is no specific height of the world, the sky is beyond. There is a circumpherence and length of the full globe.
You mean the surface area, right? Assuming the balloon is approximately spherical, you can measure the diameter, divide by two to get the radius & plug that into this formula.A=¾πr²Where A is the area, r is the radius and π is the ratio of the circumpherence to the radius of a circle. 3.14 or 22/7 are good approximations to π, also a decent calculator will have a better approximation built in. To look it up search for "pi" (that's the Greek letter's name).
