Hi there!
In 60 min, minute hand completes = 360°
In 1 min, minute hand will complete angle = 360/60 = 6°
So,
Angle made in 7 minute = 6 × 7 = 42° [ θ ]
ATQ,
θ/360 × πr²
42/360 × 22/7 × 5²
55/6
9.16 cm²
Hence,
The minute hand will form a sector of area = 9.16 cm²
[ Thank you! for asking the question. ]
Hope it helps!
