Solution:

We know that:

  • Radius: Diameter/2
  • Area of circle: (π)(r²)

Step-1: Find the radius:

  • Diameter = 22 mm
  • => Radius: 22 mm/2
  • => Radius: 11 mm

Step-2: Find the area of the circle:

  • Area of circle = (π)(r²)
  • => Area of circle = (3.14)(11²)
  • => Area of circle = (3.14)(121)
  • => Area of circle = 3.14 x 121 = 379.94 mm²
  • Diameter=22mm
  • Radius=11mm

[tex]\\ \rm\Rrightarrow Area=\pi r^2[/tex]

[tex]\\ \rm\Rrightarrow Area=(3.14)11^2[/tex]

[tex]\\ \rm\Rrightarrow Area=121(3.14)[/tex]

[tex]\\ \rm\Rrightarrow Area=379.9mm^2[/tex]
