What happens to the area of a circle if you double the original radius?
the area doubles. for example: the radius is 2. so the area is 4pi. then double the original radius of 2 to 4 and the area is 8pi. 8pi is double 4pi.
What happens if double the diameter?
Nothing happens. A person sitting next to you won't know that you did anything to your circle. But you'll have a bigger circle. The radius will be double the originasl radius. The circumference will be double the original circumference. The area will be four times the original area.
What happens to the area of a circle when the radius is doubled tripled?
The area increases as the square of the radius (or diameter). So if you double the radius you * 4 (quadruple) the area. Treble the radius, you *9 the area.
What happens to the area of a circle if you double the radius?
Since the area of a circle is S=πr2 and we intend to double the radius(2r) then the area of the new circle will be S'=π*(2r)2=4*πr2, an area 4 times greater than the initial one S'=4S.
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
