AREA OF A CIRCLE

==================================

Problem

  • what is the area of a circle if the radius is 12 meters?

Solution

Solve using the area of a circle formula where r is the radius itself

  • [tex]\bold{Formula\:||\:Area = πr²}[/tex]
  • [tex]\large\tt{\red{Area} = π(12\:m)²}[/tex]

Substitute 12 for r in the formula, multiply by the power of two then pi π = (3.14)

  • [tex]\large\tt{Area = πr²}[/tex]

  • [tex]\large\tt{Area = 3.14(12\:m)²\:m²}[/tex]

  • [tex]\large\tt{Area = 3.14(144) \:m²}[/tex]

  • [tex]\underline{\large\tt\red{452.16 = Area} }[/tex]

Final Answer

  • Therefore, the area of a circle that has a radius of 12 meters is 452.16 square meter
