Penjelasan dengan langkah-langkah:
LP & vBR
Luas permukaan
= Lp.Tabung tanpa tutup + Ls.Kerucut
= (πr(r+t)) + (πrs)
= (3,14×4,5(4,5+10)) + (3,14×4,5×13)
= (14,13(14,5)) + 183,69
= 204,885 + 183,69
= 388,575 cm²
tinggi kerucut
= √(13²-4,5²)
= √(148,75)
≈ 12,2
Volume
= V.tabung + V.kerucut
= (πr²t) + (¹/₃πr²t)
= (3,14×4,5×4,5×10) + (¹/₃×3,14×4,5×4,5×12,2)
= 635.85 + 258.579
= 894.429 cm³
