What happens to the circumference of a circle when the radius doubles?
If the radius of a circle doubles, the circumference doubles, and so does the diameter.
When you double the diameter of the area of a circle with the radius of 4 what happens to the circle area?
The radius also doubles as the diameter doubles so the new radius is now 8. This makes the area quadrupal because to find the area you must use the formula nr^2
What happens if you divide the diameter of a circle by two?
It will result to the circle's radius.
What happens to the radius of a circle when the diameter is increased by 4?
Radius is half of diameter so it increases by 2.
How is the circumference of a circle with radius 9 cm related to the circumference of a circle with diameter of 9cm?
Doubling the radius doubles the circumference.
How do the the radius and diameter of a circle compare?
The diameter of a circle is twice its 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.
If the radius of a circle is r what is the diameter of the circle?
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
What happens to the radius of a circle when the diameter is reduced by half?
The radius is also reduced by half
What happens to the circumference of a circle when the radius is doubles?
The circumference also doubles.
What is the diameter of a circle or a radius of in?
The diameter of a circle is twice its radius
When the diameter of a circle is 85.4 What is the radius of the circle?
The radius of a circle is always half of the diameter. If the diameter is 85.4, the radius is 42.7.
