Answer 1

Answer:

Cost of leveling = ₹ 19008

Step-by-step explanation:

D = 168 cm

r = 168/2 = 84 cm

H = 150 cm

Area cov. in 1 rev. = LS A of roller

= 2πrh

= 2 × 22/7 × 84 × 150

= 79200 sq. cm

Area covered in 1 rev. = 79200 sq. cm

Area covered in 800 rev. = 79200 × 800

= 63360000 sq. cm

10000 sq. cm = 1 m^2

63360000 sq. cm = 63360000/10000

= 6336 sq. m

Rate of leveling = ₹ 3 / m^2

Cost of leveling 6336 sq. m = 6336 × 3

= ₹ 19008

Hence , the total cost of leveling is ₹ 190008 .
