Solve for r: C = 2pi(r). r = C over 2 pi r = 2 c all over pi r = C over pi r = pi times C all over 2

A)r = C over 2 pi
B)r = 2 c all over pi
C)r = C over pi
D)r = pi times C all over 2

Answer: A)r = C over pi 2 - C/2π

Step by-step explanation:

Hence C × 12π = 2πr 2 πor C2π = ri.e.r = C2π

C=2pi(r)
divide both sides by 2pi
C/(2pi)=r
in fancy form it looks like this:

(C)/(2\pi)=r

so answer is A
