Kerucut dan belahan bola di samping. diket diameter krucut 21mm dan tinggi krucut 4mm hitung volume bandul

diameter = 21mm
tinggi kerucut = 4mm

V. kerucut = ¼×⅓πd²t
= ¼×⅓×22/7×21×21×4
= 22×21
= 462mm³

diamater = 21mm maka r = 10,5mm

V. ½bola = ⅛×2/3πd³
= ⅛×2/3×22/7×21×21×21
= ⅛×44×21×21
= ⅛×19404
= 2425,5mm³

V. bandul =
462mm³ + 2425,5mm³ = 2887,5mm³

semoga membantu
