Answer:
1980 m sq
Step-by-step explanation:
length of roller=h=1m
diameter of the roller=84cm
since radius of the roller = r=84%2
=42 cm
42%100m
Given,
the rollar takes 750 complete revolutions to level the whole road
Area of road=750×Area covered in 1 revolution
=750×lateral surface area of cyclinder
=750×2(pie)rh
=750×2×22%7×42%100×1
=750×2×22×6%100×1
=1500×132%100
=15×132
=1980m(sq.)
