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 = r
Circumference = 2πr
Double the radius:
New radius = 2r
New circumference = 4πr
Increase in circumference = 4πr - 2πr = 2πr = (2πr/2πr) X 100%
=100%

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 is the circumference of a circle when the radius is 2.3 m?
4.6m. The circumference is double the radius.
As the diameter of the circle increases what happens to the circumference?
The circumference of a circle increases with an increase in the radius as it is directly proportional its radius.
How do find the circumference of a circle if you have the radius?
easy you just double it. Additional answer No, that's incorrect. If you double the radius you get the diameter. To get the circumference you multiply the radius by 2 then by 3.142. 3.142 is known as pi
How do you find the circumference of a circle with the radius of 22.3MM?
Double the radius and multiply by pi

What is the circumference of a circle when the radius is 2.3 m?
4.6m. The circumference is double the radius.
What is the circumference of a circle with a radius of 15.5cm?
the equation for the circumference is Pi * double the radius which is 3.1416 * 15.5 * 2 The circumference of a circle with a radius of 15.5cm is 97.3cm.
As the diameter of the circle increases what happens to the circumference?
The circumference of a circle increases with an increase in the radius as it is directly proportional its radius.
What happens to the circumference of a circle if you double the radius?
The circumference also doubles.

Double the radius and multiply by pi
What is the circumference of a 3 inch circle?
circumference= pi(3.14) by the diameter. if your given the radius, double the radius and times by pi.
How do you get the diameter of circle if you don't have the circumference?
Double the radius.
If the radius of a cricle is increased by 75 percent then its circumference will be increased by?
The cricle's circumference is a linear function of its radius, so they change in direct proportion.If the radius increases by 75%, the circumference also increases by 75%.
If the circumference of a circle is increased by 50 then the area will be increased by?
there is no constant that will calculate this, since circumference is calculated with only radius and area with radius squared. you will have to calculate the radius using the initial circumference and then the radius again for the new circumference (with the 50 added). then calculate an area for each radius..then you can see the increase.
What is the circumference of a circle with radius of 4.5 m?
The circumference of any circle is (pi) x (diameter),and of course, the diameter is double the radius.
