Hitunglah volume bangun gabungan di atas!!
Jari-jari (r) :
= √(29² - 20²)
= √(841 - 400)
= √441
= 21 cm
Volume Tabung :
= πr²t
= 22/7 × 21² × 12
= 264/7 × 441
= 264 × 63
= 16.632 cm³
Volume Kerucut :
= ⅓ × πr²t
= ⅓ × 22/7 × 21² × 20
= ⅓ × 440/7 × 441
= ⅓ × 440 × 63
= 9.240 cm³
Volume Gabungan :
= Volume Tabung + Volume Kerucut
= 16.632 + 9.240
= 25.872 cm³
