What happens to the circumference of a circle when the radius is doubles?
The circumference also doubles.
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.
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%.
What happens to the circumference of a circle if you double the radius?
The circumference also doubles.

If the radius of a circle halved what will happen to the circumference?
It will also be halved as circumference = 2Ï€r
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.
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.
Is the radius of a circle a chord also?
No. A chord is a straight line joining two points on the circumference of a circle whereas a radius joins only one point on the circumference to the circle centre. A diameter is a straight line joining two points on the circumference (via the circle's centre) and so is also a chord. (Yes, but the question is about a radius, not a diameter!)
What happens to the area of a circle if you triple a radius?
When you triple the radius of the circle . . . -- The diameter also triples. -- The circumference also triples. -- The area is multiplied by 9 .
