r² = 58² - 40²
r² = 3364 - 1600
r² = 1764
r = 42 cm
Volume 1 = V tabung + V kerucut
(πr²t) + (1/3πr²t)
(22/7 x 42 x 42 x 70) + (1/3 x 22/7 x 42 x 42 x 40)
388.080 + 73.920
462.000 cm³
Volume 2 = V tabung + V kerucut
(πr²t) + (1/3πr²t)
(22/7 x 42 x 42 x 20) + (1/3 x 22/7 x 42 x 42 x 40)
110.880 + 73.920
184.800 cm³
Volume akhir = V1 - V2
= 462.000 - 184.800
= 277.200 cm³
Maaf kalau salah^^
v.berkurang=50cm dari v.tabung
v=v.tabung dengan tinggi 50cm
πr²t=22/7 x 42cm x 42cm x 50cm
v=277200cm³
