Question

The circumference of a circle can be found using the formula C = 2r.

Which is an equivalent equation solved for r?

r = C
r = C(2)
r = r equals StartFraction C Over 2 pi EndFraction.
r = r equals StartFraction 2 pi Over C EndFraction.

Answer 1

r = C/2

Explanation:

C = 2r Divide both sides by 2;

C/2 = r Replace sides;

r = C/2.
