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.
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.
Nothing - if you double the radius you will get the diameter. The area of the circle will remain the same
The result is 9 time the original.
The circumfrence would double Example : C of 5 cm radius circle = 3.14 *2*5 C=3.14 C of 10cm radius circle = 3.14*2*10 C =62.8
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.

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.
The circumference also doubles.
The result is 9 time the original.
the area of the circle will be 1/4 of its original area
the area of the original is 4 times the new value.
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.
You get 2 circles of diameter. If you were trying to find a perimeter, Never double the diameter. If you have a radius, You have to double it to get a perimeter.
The circumfrence would double Example : C of 5 cm radius circle = 3.14 *2*5 C=3.14 C of 10cm radius circle = 3.14*2*10 C =62.8
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.
it is cut down by a factor of four since it is proportional to square of radius
