Sebuah kerucut memiliki jari jari 14 cm dan tinggi 28 cm. Hitunglah volume kerucut tersebut
![]()
Penjelasan dengan langkah-langkah:
volume = 1/3πr²t
volume = 1/3 × 22/7 × 14² × 28
volume = 1/3 × 22 × 14/7 × 14 × 28
volume = 1/3 × 22 × 2 × 14 × 28
volume = 1/3 × 44 × 14 × 28
volume = 1/3 × 616 × 28
volume = 1/3 × 17.284
volume = 5.761,3... cm³
v = [tex]\frac{1}{3}[/tex] × π × r² × t
v = [tex]\frac{1}{3}[/tex] × [tex]\frac{22}{7}[/tex] × 14 × 14 × 28
v = [tex]\frac{1}{3}[/tex] × 22 × 2 × 392
v = [tex]\frac{1}{3}[/tex] × 17284
v = [tex]\frac{17284}{3}[/tex]
v = 5.761,3 cm ³
