given length of the minute hand clock = 14cm
it means radius of the circle is r = 14 cm
=the angle moves by the minute hand in 30 min =180
= the angle moves by the minute hand in 1 minute =180/ 36 = 6
=the angle moves by the minute hand in 5 minutes = 30 degree
using the formula,area of sector of circle
Φπr²/360 = 22 × 14 × 2 / 12 = 616/12 = 154/3 cm²
May this will help you
