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=(3.14)11^2[/tex]
[tex]\\ \rm\Rrightarrow Area=121(3.14)[/tex]
[tex]\\ \rm\Rrightarrow Area=379.9mm^2[/tex]
