minute hand = 14cm
therefore,
radius = 14
therefore ,
area = 22/7 * 14 *14
= 614 cm2
minute hand movement = area by radius
616 /14
= 44
minute hand = 14cm

a minute takes one complete rotation for one hour, so for two hours it will take 2 complete rotations.
radius of the circle is the length of the minute hand.
r = 14 cm
The distance travelled is the circumference of the circle.
distance = 2*2*pi*r = 4*22/7*14 = 176 cm
