If the radius of a circle of area A and circumference C is doubled, the new circumference of the circle, in terms of C, will be equal to 2C.

The area (A) of a circle is given by:

[tex] A = \pi r^{2} [/tex]   (1)

And a circumference (C) is:

[tex] C = 2\pi r [/tex]   (2)

Where:

r: is the radius

If the radius of a circle and circumference is doubled, the new circumference of the circle is:

[tex] C_{2} = 2 (2 \pi r) = 2C [/tex]

Therefore, the new circumference of the circle in terms of C is equal to 2C.
