Biaya untuk mengecat drum

[tex] \sf Luas = 2 \times \pi \times r(r + t)[/tex]

[tex] \: \: \: \: \: \: \: \: \: \: \sf = 2 \times \frac{22}{7} \times 35(35 + 90)[/tex]

[tex] \: \: \: \: \: \: \: \: \: \: \sf = \frac{44}{7} \times 35(125)[/tex]

[tex] \: \: \: \: \: \: \: \: \: \: \sf = 44 \times 5(125)[/tex]

[tex] \: \: \: \: \: \: \: \: \: \: \sf = 220(125)[/tex]

[tex] \: \: \: \: \: \: \: \: \: \: \sf = 27.500 \: {cm}^{2} [/tex]

.

[tex] \sf Biaya = luas \times perbiaya[/tex]

[tex]\sf Biaya = 27.500 \times 10,00[/tex]

[tex]\sf Biaya = 275.000[/tex]
