If you double the radius of a circle will the circumference also double?

since the equation to get circumference is diamiter X pi, and the diamiter is 2x the radius, yes it would double the C of the circle
ie
before
radius is 2, so diamiter is 4
4 X Pi 12.57...
radius is 4 so the diamiter is 8
8 X pi = 25.13...
that would double it.

When the radius of a circle is doubled what happens to the circumference?
since C=2Pixr, if we double r, we need to double C also. 2C=2Pix 2r
A circle has a radius of 12 yards what is its circumference?
We know that the radius is half of the diameter, and also that a circle's diameter multiplied by pi is the circumference, so we multiply 12 by 2 to get 24, then we multiply this by pi, so we can either express this as 24π units, or we can assume pi to be 3.1415926 and multiply this by 24 to get 75.3982224 units.
When the diameter of a circle doubled what happens to the circumference of the circle?
When the diameter of the circle doubled, its circumference also doubled.However, its area increased to 4 times the original area, while nobody was looking.
What is the formula for circumference?
There are 2 formulas for finding the circumference of the circle.If the radius diameter is given,we use the formula �d.When the radius is given,we use the formula 2�R. * * * * * But there are also other formulae for when the area is given, or the length of an arc and the angle subtended at the centre or on the circumference are known. Plus many more. Basically, the question is too poorly specified to find a single answer. Also, the above formulae assume that the shape is a circle. But it could be an ellipse, for example.
What jobs use circumference and area of a circle?
carpenters, and also architects haha
What happens to the circumference of a circle if you double the radius?
The circumference also doubles.
What happens to the circumference of a circle when the radius is doubles?
The circumference also doubles.
Will the circumference increase by 200 percent if you double the radius?
If you double the radius of a circle, you also double its circumference.It's now 200% of what it was originally ... an increase of 100% .See rigorous proof below.===========================================Let radius = rCircumference = 2πrDouble the radius:New radius = 2rNew circumference = 4πrIncrease in circumference = 4πr - 2πr = 2πr = (2πr/2πr) X 100%=100%
If you triple the radius of a circle how is its circumference affected?
The circumference of a circle = 2*pi*r. if you triple r, the circumference is tripled also.
Formula of circumference?
Formula of Circumference of a circle: 3.14*Diameter of the circle. You could also do: 3.14*3.14*radius.
How can you find the circumference of a circle with radius or diameter?
The circumference of a circle is equal to its diameter times pi. This is also equal to two times its radius times pi.
If the radius of a circle halved what will happen to the circumference?
It will also be halved as circumference = 2Ï€r
When the radius of a circle is doubled what happens to the circumference?
since C=2Pixr, if we double r, we need to double C also. 2C=2Pix 2r
What is the circumference of a circle when the radius doubles or trebles?
The circumference also doubles or trebles. The circumference is directly proportional to the radius, with the constant of proportionality = 2*pi.
What happens to the circumference of a circle when the radius is increased by 50 percent?
The circumference is directly proportional to the radius. So increasing the radius by 50% causes the circumference to also increase by 50%.
How do you find the radious of a circle?
The radius of a circle is any straight line from the centre of the circle to its circumference. The radius can also refer to the length of this line.
What is the circumference of a circle when the arc is 30 degrees and minor arc is 8?
The circumference of a circle is 360 degrees. The circumference of a circle is also 2*pi*radius or diameter*pi.
