Panjang garis pelukis sebuah kerucut 34 cm. jika jari jari kerucut 16 cm dan pi=22/7. volume kerucut adalah.
Pake caranya ya kak

Garis pelukis = s jari jari = r tinggi = t t= √s²-r² = 34²-16² = √1156-256 =√900 = 30 cm v kerucut = 1/3.π.r².t = 1/3.22/7.16.16.30=8.045,71

Diket :- garis pelukis kerucut =34 cm - r= 16 cm Ditanya: Volume kerucut Jawab : V = 1/3 x x r^2 x t t = √34^2 - 16^2 = √900 = 30 V= 1/3 x 3,14 x 16 x 16 x 30 = 803,84
jari jari = r
tinggi = t
t= √s²-r² = 34²-16² = √1156-256 =√900 = 30 cm
v kerucut = 1/3.π.r².t = 1/3.22/7.16.16.30=8.045,71
- r= 16 cm
Ditanya: Volume kerucut
Jawab : V = 1/3 x x r^2 x t
t = √34^2 - 16^2
= √900
= 30
V= 1/3 x 3,14 x 16 x 16 x 30
= 803,84
