volume seluruhnya =
tiap 1cm3 = 10gram
60288cm3 = 60288gram = 60,288Kg (C)
t² = 20² - 12² = 400 - 144 = 256
t = √256 = 16 cm
Volume bandul :
= V.kerucut + V1/2 bola
= 1/3 πr²t + 2/3 πr³
= 1/3 πr² (t + 2r)
= 1/3 (3,14)(12)² (16 + 2(12))
= 150,72 (16 + 24)
= 150,72 (40)
= 6028,8 cm³
karena berat bandul setiap 1 cm³ = 10 gr, maka berat keseluruhan adalah :
Berat bandul = 6028,8 x 10 = 60.288 gr = 60,288 kg
