tolong ya pake caranya juga

D = 14 cm
r = 1/2 x 14 = 7 cm

L = 2πrt
440 = 2 . 22/7 . 7 . t
440 = 44 t
t = 440 / 44
t = 10 cm

V = πr²t
V = 22/7 . 7 . 7 . 10
V = 22 . 7 . 10
V = 1.540 cm³

L.selimut tabung = 2 × phi × r × t
440 = 2 × 22/7 × 7 ×t
440 = 44 t
440 ÷ 44 = t
10 cm = t
V.tabung = phi × r^ × t
= 22/7 × 7 ^× 10
= 1.540 cm3
Klo gk slah tapi kok gk ada jawabannya
