Area of a circle = πr² = 22/7 × 10.5 × 10.5 = 346.5 cm²
Or, Area of a circle = 22/7 × 10.5 × 10.5
Or, Area of a circle = 346.5 cm²
Circumference of a circle = 2πr
Or, Circumference of a circle = 2 × 22/7 × 10.5
Or, Circumference of a circle = 66 cm
Therefore, the area of a circle = 346.5 cm² and the circumference of a circle = 66 cm
