Volume sebagian kaleng A :
VA = 1/2 × π × r × r × t
= 1/2 x 22/7 × 21 × 21 × 39
= 37027 cm^3
tinggi permukaan tabung B :
tB = VA : (π × r × r)
= 37027 : (22/7 × 14 × 14)
= 37027 : 616
= 43,875 cm
= 43,9 cm (B)

volume = phi × r^2 × t
volume = 22/7 × 21 × 21 × 39
volume = 54.054
Jika dituangkan,
volume A = volume B
54.054 = phi × r^2 × t
54.054 = 22/7 × 14 ×14 × t
54.054 = 616 × t
t = 87,75
Jadi tinggi permukaan cat B adalah 87,75 cm
maaf kalau salah
semoga membantu
