Respuesta :
d = 2r
C = 2 Pi r = Pi d
K = Pi r2 = Pi d2/4
C = 2 sqrt(Pi K)
K = C2/4 Pi = Cr/2
C=2r
Divide 2 by r
C/2=r
you do the same on the other side of the equation and get
r=C/2....r equals C divided by 2
Divide 2 by r
C/2=r
you do the same on the other side of the equation and get
r=C/2....r equals C divided by 2
