• The length of the miniute hand of a clock is 20 cm

$\large \bold{\underline{\sf{\blue{To\:Find}}}}$

• the area swept by the minuite hand in 10 min

$\large \bold{\underline{\sf{\blue{Solution}}}}$

Length of the minute hard of a clock

r = 20

Angle swept by minute hand in 10 minutes

Ø = 30°

Area swept by minute hand in 10 minutes

= Ø/360° x πr²

= 30/360° x 22/7 x 20 x 20

= 104.76 cm²

∴ the area swept by the minute hand in 10 min is 104.76 cm²
