Volume kerucut
r = 3 cm
s = 5 cm
t² = s² - r²
= 5² - 3²
= 25 - 9
= 16
t = √16
= 4 cm
Volume = 1/3.π.r².t
= 1/3 x 3,14 x 3² x 4
= 1/3 x 3,14 x 9 x 4
= 37,68 cm³
Volume setengah Bola
r = 3 cm
Volume = 1/2 x 4/3.π.r³
= 1/2 x 4/3 x 3,14 x 3³
= 1/2 x 4/3 x 3,14 x 27
= 56,52 cm³
Volume Bandul
V = Volume Kerucut + Volume setengah bola
= 37,68 cm³ + 56,52 cm³
= 94,2 cm³
Berat Bandul
Berat = 94,2 cm³ x 0,05 gram/cm³
= 4,71 gram
