$\huge\large \fbox \red{Given :}$

• Diameter of circle = 2.1 m

• So , the radius of circle ( r )= 1.05 m

$\huge\large \fbox \red{Find \: :}$

• Area of circle

$\huge\large \fbox \red{Solution :}$

Area of circle = π r ²

= 22/7 × 1.05 m × 1.05 m

= 22/7 × 1.1025 m ²

= 22 × 0.1575 m²

= 3.465 m²

Hence , the area of circle is 3.465 m ²
