Question

Find the no of revolutiontaken by a wheel of radius 35 cm at a speed of 66hm per hour

Answer 1

Ans ➡️ The circumference of circle is 2πr.

Using this we get to know that circumference is 220 cm.

Now the distance covered in one minute is

6600000/60

=110000cm per minute.

Total number of revolution to maintain the same speed is

110000/220

=500 revolution.

 Hope it helps.☺️☺️✌️✌️❤️❤️
