S / 9 = C / 10 = R / (π / 20) = q
S = 9q
C = 10q
N = ⁵√[(10(10q) + 12(9q)) / (10q - 9) + 35]
N = ⁵√[(100q + 108q) / q + 35]
N = ⁵√[208q / q + 35]
N = ⁵√[208 + 35]
N = ⁵√243
N = 3

S / 180 = C / 200 = R / π = k
S = 180k
C = 200k
R = πk
S + C + R = 383,1416
180k + 200k + πk = 380 + 3,1416
380k + πk = 380 + π
k(380 + π) = 380 + π
k = 1
R = πk
R = π rad

S / 180 = C / 200 = R / π = k
S = 180k
C = 200k
R = πk
(200k + 2(πk)) / (200k - 2(πk)) = (180k + 3π) / (180k - 3π)
(200k + 2πk) / (200k - 2πk) = (180k + 3π) / (180k - 3π)
2k(100 + π) / (2k(100 - π)) = 3(60k + π) / (3(60k - π))
(100 + π) / (100 - π) = (60k + π) / (60k - π)
60k = 100
k = 100 / 60
k = 5 / 3
R = πk
R = π(5 / 3)
R = 5π / 3 rad
