If you double the original radius, the area will become 4 times what it was.

The area of a circle is pi*r^2 = A. If our new radius (lets say x) is double (x=2r), we have pi*x^2 = pi*(2r)^2, which equals 4*pi*r^2 = 4A, or 4 times the original area.

What happens to the area of a circle if yo double the radius?

Nothing - if you double the radius you will get the diameter. The area of the circle will remain the same


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 to the area of a circle when the radius is triple?

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 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 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.


What happens to the area of the circle when the diameter is doubled?

As the area of a circle A equals pi times the radius squared, and doubling the diameter means multiplying the radius by four, the area is multiplied by 16 when you double the diameter.


If the radius of a circle is doubled what happens to the area of the circle?

the area of the circle is increased by 400%


If the radius of a circle is doubled what happens to the area?

It quadruples. The area of a circle is Pi (about 3.14159) times the radius squared. So if you double the radius (say from 2m to 4m), you area will change from 4*Pi to 16*Pi (4 times what it was originally).


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 to the area of a circle if the radius is tripled?

The circle becomes an oval


When the radius of a circle is doubled what happens to the area?

It quadruples.
