Jawab:
1540 [tex]cm^{2}[/tex]
*maaf bila salah, semangat dan bintangnya
Penjelasan dengan langkah-langkah:
= Tabung = [tex]\pi r^{2} *t[/tex]
= Kerucut = [tex]\frac{1}{3} \pi r^{2} *t[/tex]
Diketahui =
> diameter = 14, r = 7
> tinggi kerucut = 12
> tinggi tabung = 18-12 = 6
Jawab =
Volume tabung + Volume kerucut
= ([tex]\frac{22}{7}[/tex]*[tex]7^{2}[/tex]*6) + ([tex]\frac{1}{3}[/tex]*[tex]\frac{22}{7}[/tex]*[tex]7^{2}[/tex]*12)
= (22*7*6) + (22*7*4)
= 924 + 616
= 1540 [tex]cm^{2}[/tex]
