In the above question it is given that the diameter of a wheel is 84cm and it is said to find the area covered by the wheel in 12 revolutions and then here is the answer :-
Diameter = 84 cm
Radius (r) = 84/2 = 42 cm
Area covered in 1 revolution = Circumference = 2πr
= 2×22/7×42
= 264 cm
Area covered in 12 revolutions
= 12×264
= 3168 cm
Here is the answer and hope it will help you.
