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 --
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
Hope it helps you :) Have a wonderful day ahead #

Answer:
Diameter = 2r =84cm
Distance covered in one revolution = circumference = 2πr
22
= 7
x 84 = 264cm
Thus, to cover a distance of 264cm, number of
revolution = 1
To cover a distance of 792 metres = 79200cm,
79200
264
number of revolutions =
= 300
