Penjelasan dengan langkah-langkah:
luas permukaan tabung : 2.phi.r
1406,72=2x 3,14x 8(8+t)
(8+t)= 1406,72/50,24
t= 28 cm- 8 cm
t=20 cm
L = 2πR(R + T)
1.406,72 = 2(3,14(8(8 + T)
1.406,72 = 6,28(8(8 + T)
1.406,72 = 50,24 × 8 + T
50,24 × 8 + T = 1.406,72
8 + T = 1.406,72/50,24
8 + T = 28
T = 28 - 8
T = 20 CM
