Question

The circumference of a circle, C, depends on the radius of the circle and can be calculated using the formula: C=2piR rearrange this formula so that it is solved for the variable r.

Answer 1

r =
`(C)/(2\pi )`

Explanation:

given the formula for calculating the circumference (C) of a circle

C = 2πr ( r is the radius )

isolate r by dividing both sides by 2π

`(C)/(2\pi )` = r
