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.
