hitunglah volume bangun diatas

jarijari alas kerucut bawah = r= 12 cm
tinggi seluruh kerucut = t = 42 cm
π = 22/7
volume kerucut = 1/3πr² t
= 1/3 × 22/7 × 12 × 12 × 42
= 1/3× 22× 144×6
= 44 × 144 = 6.336 cm³

jari-jari alas kerucut atas = 6 cm
tinggi = 42 - 21 = 21 cm
volume kerucut atas =1/3πr²t
= 1/3 × 22/7 × 6×6 ×21
= 1/3 × 22 × 36 × 3
= 22×36 = 792 cm³
volume kerucut terpancung =
6.336 - 792= 5.544 cm³

maaf klu salah , segra dihapus ,trimakasih
