1.	The diameter of a roller is 80 cm and its length is126 cm. It takes 750 complete revolutions movingonce over to level a garden. Find the area of thegarden.
Answer» Answer: AREA COVERED in one REVOLUTION = 2×pie×40×126 Hence area covered in 750 revolution = 2×(22/7)×40×126×750 =2×22×40×18×750 = 44×3000×18 = 44×54000 multiply these two numbers, you will get answer
