Answer:4400cm
Step-by-step explanation:
Given diameter=70cm
This implies radius =35cm
Circumference of wheel
=2πr
=2×(22/7)×35
=2×22×5
=220cm
Now
Distance travelled by wheel in 20 revolutions
=20× circumference of wheel
=20×220
=4400cm
Therefore 4400cm distance will be travelled by the wheel in 20 revolutions.
