d = a - 2bc
C= pi * D This is the formula for circumference.
d=a-2bc
Divide both sides by 4: c = d/4
(a-d)/2c=b
d = a - 2bc
d = -196
If: a = b+c+d Then: c = a-b-d
D - 9 = 9 d = 9 + 9 d = 18
C= pi * D This is the formula for circumference.
d=a-2bc
Divide both sides by 4: c = d/4
(a-d)/2c=b
6d = c Divide both sides by 6: d = c/d
(a+d)/2b=c
d = r t t = d / r
c= (a+d) / 2b
