Step-by-step explanation:

Let the length h of minute hand be x.

Distance moved by it in 1 hour = circumference of a circle with radius x.

Circumference of a circle= 2 * π * r

Circumference= 2 * π * x

= 2πx

But, the distance moved by it is 22π

=> 2πx= 22π

=> x = 22π/2π

=> x = 11

Therefore, the length of the minute hand is 11 cm in length.
