= 23, 561. 945 cm

Step-by-step explanation:

If the fan does 300 rev per min;

300 rev : 60 sec

x rev : 15 sec

x = 300 * 15 / 60

x = 75 rev

One revolution of the point on the blade is equal to the circumference of the circle with a radius of 10 cm. Therefore;

2πr

2* 3.14 * 10

= 62.83 cm

75 revolution will be;

75 * 62.83 cm

= 4712.39 cm
