length= 14 cm
angle= 1 min = 60/360 = 6 degree
area swept = 6/360 * 22/7 * 14 * 14
= 1/60*22*2*14
= 1/30*22*14
= 1/15*22*7
= 154/7
= 10.266cm²

area covered by
minute hand in 1 min. = 1 complete circle
dia = length of minute hand = 14 cm
then area covered = A = πr^2 ( r square )
= 3.142*(14)^2
=615.832 cm^2
