Penjelasan dengan langkah-langkah:
Total LP = Lp 1/2 bola+Lp tabung
= 2πr² + 2πr(r+t)
= 2πrr + 2πr(r+t)
faktorkan = 2πr (r+r+t)
[tex] = 2 \frac{22}{7} \times 14(14 + 14 + 30)[/tex]
[tex] = 2.22.2(58)[/tex]
[tex] = 88 (58)[/tex]
[tex] = 5.104cm^{2} [/tex]
Total Volume :
[tex] = v \: \frac{1}{2} bola + v \: tanbung[/tex]
[tex] = \frac{2}{3} \pi {r}^{3} + \pi r^{2}t[/tex]
kalau di jabarkan jadinya
[tex] = \frac{2}{3} \pi r r r + \pi r r t[/tex]
kita faktorkan maka:
[tex] = \pi r r ( \frac{2}{3} + r + t)[/tex]
[tex] = \frac{22}{7} \times 14 \times 14( \frac{2}{3} + 14 + 30)[/tex]
[tex] = 22 \times 14 \times 2( 2 + 14 + 10)[/tex]
[tex] = 616(26)[/tex]
[tex] = 16.016 {cm}^{3} [/tex]
