Answer:
Step-by-step explanation:
Diameter of the wheel is 84 cm
so circumference of the wheel
=π×diameter
=22/7×84cm=22×12cm=264cm
distance covered in one revolution=
circumference of the wheel.
In 1 sec there are 4 revolutions
so distance covered in 1sec=
4×264cm=1056cm
so speed of the wheel is 1056cm/sec
