Minute hand complete full circle in 1 hour.
Angle swept by minute in 1 hour (60 minute )=360°
Angle swept by minute hand in 1 minute = 360/60 = 6°
Angle swept by minute hand in 5 min=6×5=30°
θ=30°, r=14 cm
Area swept by minute hand = Area of sector
= θ/360 ×πr²
=30/360 × 22/7 × (14)²
= 1\12 × 22\7 × 14 × 14
Area swept by minute hand= 154/3 cm²
