What is the formula for the circumference of a circle using the diameter measure?
Multiply the diameter times pi.
What is the true way to find the circumference of a oval?
Not quite sure what you mean by "true way". You can measure it with a string or a similar flexible object. Or you can measure length and width, and - assuming it is an ellipse - use the formula for the circumference of an ellipse - or rather, an approximation formula.
Does the arc length equals the measure of the arc?
No, in order to fine the arc length you need a formula which is: Circumference x arc measure/360 degrees
What is the formula for the circumference of a circle if the diameter is 8.70 m?
The formula for the circumference of a circle is the same, whatever its diameter. Circumference = pi*diameter.
How do you measure circumference of a bottle?
Circumference = 2*pi*r r(radius) * 2 = diameter So. assuming the bottle is fairly a circle, measure across the bottom to get the diameter and then divide that in half for the radius and use the circumference formula. Of course a bottle is not quite a perfect circle everywhere and you might need calculus to get a proper circumference. I am thinking vector calculus.

Why would you use a formula to determine the circumference of a circle rather than measuring the circumference?
Because the circumference of a circle isn't a straight line its hard to measure, even if you have a flexi-ruler, your never going to be able to line it up to get an exact measurement. Therefore its much easier to measure the diameter and use the formula
Does the arc length equals the measure of the arc?
No, in order to fine the arc length you need a formula which is: Circumference x arc measure/360 degrees
What is the formula of a circumference?
circumference=r2pi
Radious formula for a cicrle?
It is not clear whether you want the formula of some aspect (area or circumference) of a circle when given its radius or a formula for its radius when given some characteristic measure of the circle.
Why the formula of circumference of circle always constant?
Because:- circumference/diameter = pi and when the formula is rearranged circumference = pi*diameter

The formula for the circumference of a circle is the same, whatever its diameter. Circumference = pi*diameter.

How do you determine the circumference of a circle if you know the radius?
use the formula pi*diameter = circumference and the formula diameter = 2*radius and combine them 2pi*radius = circumference now you have a formula that you can just plug you numbers into. if you have 3 as your radius, then this is how to find the circumference 2pi*3=circumference 6.28*3=circumference 18.84=circumference
Formula for finding the circumference of cone?
There is no circumference of a cone, but, we only do the circumference of the circle. the formula for the circle is pi times D. D= Diameter
What is the measure of the radius 20.1?
You mean how to measure circumference and area of a circle, so there are some formulas to measure it.Now to measure circumference of the circle the formula is 2.pi.r(remember pi is always 22/7.Here r is 20.1).So applying this formula lets find the circumference, that is 2x22/7x20.1=126.34285714285714285714285714286Now to find area of a circle you have to apply the formula that is pi.(r)square.Lets find the area applying this formula, 22/7x(20.1)square=(1269.7457142857142857142857142857)square that`s it.More:Instead of taking pi as 22/7 you can take it as 3.14.But if you will calculate 22/7 the answers will be 3.1415926535897932384626433832795 so in short take it 3.14.Thanks
