  • A Tin can of pineapple juice has a radius of 10cm and a height of 24cm.

How many square centimeters of tin were used to make the can?

[tex]\tt{A.\: 21.352cm^{2}}[/tex]

[tex]\tt{B.\: 213.52cm^{2}}[/tex]

[tex]\tt{\underline{\large{\bold{C.\: 2,135.2cm^{2}}}}}[/tex]

[tex]\tt{D. \:3,135.2cm^{2}}[/tex]

[tex]\large{•••••••••••••••••••••••••••••••••••••••••••••••••••••••••••}[/tex]

Formula:

[tex]\tt{SA=2πr^{2}+2πrh}[/tex]

Solution:

[tex]\tt{SA=2π(10cm)^{2}+2π(10cm)(24cm)}[/tex]

[tex]\tt{SA=2π(100cm)+2π(240cm)}[/tex]

[tex]\tt{SA=6.28(100cm)+6.28(240cm)}[/tex]

[tex]\tt{SA=628cm+1,507.2cm}[/tex]

[tex]\tt{\large{\bold{SA=2,135.2cm^{2}}}}[/tex]
