Step-by-step explanation:

2πr = 750

or, r = 750 /2π

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.)
