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
The measure of JKL is 75 degrees
