Berdasarkan gambar tersebut, terdapat dua komponen yang perlu dihitung, yaitu:
[tex]LPTB = 2 \times \pi \times r \times (r + t)[/tex]
[tex]~~~~~~~~~~~~=2 \times \frac{22}{7} \times 7 \times (7 + 4)[/tex]
[tex]~~~~~~~~~~~~=2 \times \frac{22}{\cancel7} \times \cancel7 \times (7 + 4)[/tex]
[tex]~~~~~~~~~~~~=2 \times 22 \times 11[/tex]
[tex]~~~~~~~~~~~~=2 \times 242[/tex]
[tex]~~~~~~~~~~~~=484 \: cm {}^{2} [/tex]
[tex]STK = \pi \times 2 \times r \times t[/tex]
[tex]~~~~~~~~~~= \frac{22}{7} \times 2 \times 7 \times 4[/tex]
[tex]~~~~~~~~~~= \frac{22}{7} \times 2 \times 28[/tex]
[tex]~~~~~~~~~~= \frac{22}{7} \times 56[/tex]
[tex]~~~~~~~~~~= \frac{22}{\cancel7} \times \cancel56 {}^{8} [/tex]
[tex]~~~~~~~~~~=22 \times 8[/tex]
[tex]~~~~~~~~~~=176 \: cm {}^{2} [/tex]
[tex]Luas ~Permukaan=LPTB + STK[/tex]
[tex]~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~=484 + 176[/tex]
[tex]~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~=\boxed{660 \: cm {}^{2} } \: \: \: \boxed{NO~OPSI}[/tex]
[like aja jgn dirate, ratenya biarin 1.0]
