1570 = 2 3,14 10 t
t = 1570/62,8
t = 25 cm
Lp = 2 pi r ( r+t)
= 2.3,14.10.35
= 2198cm^2
luas alas = luas atap
luas alas = Πr²
= 3,14 ×10×10
= 314 cm²
luas permukan = luas alas + luas selimut + luas atap
luas permukaan = 314 + 1570 + 314
= 2198 cm²
jadi,luas permukaan tabung tersebut adalah 2198 cm²
