PROBLEM NUMBER 1

  • [tex] \red{{\tt{1.r=5 \: cm}}}[/tex]

FORMULA:

  • [tex] \red{{\tt{A ⟹ πr²}}}[/tex]

SOLUTION:

  • [tex] \red{{\tt{A ⟹ πr²}}}[/tex]
  • [tex] \red{{\tt{A ⟹ (3.14)(5cm)²}}}[/tex]
  • [tex] \red{{\tt{A ⟹ (3.14)(25cm²)}}}[/tex]
  • [tex] \red{{\tt{A ⟹ 78.5cm²}}}[/tex]

so the area of a circle is [tex]\fcolorbox{bluw}{white}{78.5cm²} [/tex]

PROBLEM NUMBER 2

  • [tex] \red{{\tt{2.r=10 \: cm}}}[/tex]

FORMULA:

  • [tex] \red{{\tt{A ⟹ πr²}}}[/tex]

SOLUTION:

  • [tex] \red{{\tt{A ⟹ πr²}}}[/tex]
  • [tex] \red{{\tt{A ⟹ (3.14)(10cm)²}}}[/tex]
  • [tex] \red{{\tt{A ⟹ (3.14)(100cm²)}}}[/tex]
  • [tex] \red{{\tt{A ⟹ 314cm²}}}[/tex]

so the area of a circle is [tex]\fcolorbox{bluw}{white}{314cm²} [/tex]

[tex]_________________________________________[/tex]

PROBLEM NUMBER 3

  • [tex] \red{{\tt{3.r=13 \: cm}}}[/tex]

FORMULA:

  • [tex] \red{{\tt{A ⟹ πr²}}}[/tex]

SOLUTION:

  • [tex] \red{{\tt{A ⟹ πr²}}}[/tex]
  • [tex] \red{{\tt{A ⟹ (3.14)(13cm)²}}}[/tex]
  • [tex] \red{{\tt{A ⟹ (3.14)(169cm²)}}}[/tex]
  • [tex] \red{{\tt{A ⟹ 530.66cm²}}}[/tex]

so the area of a circle is [tex]\fcolorbox{bluw}{white}{530.66cm²} [/tex]
