Question

Halla R En:
2s+3c=120

Answer 1

se sabe que:

S/180 = C/200 =R/π  

ENTONCES:
S=180K
C=200K
R=πK

reemplazando:
2(180k) + 3(200k) = 120
360k + 600k = 120
960k = 120
k = 120/960
k = 1/8

entonces:

R = π*1/8

R =π/8

esta es tu respuesta

Answer 2

Respuesta:

S/180 = C/200 =R/π  

ENTONCES:

S=180K

C=200K

R=πK

reemplazando:

2(180k) + 3(200k) = 120

360k + 600k = 120

960k = 120

k = 120/960

k = 1/8

entonces:

R = π*1/8

R =π/8
