The diameter of a garden roller is 1.4m and it is 2m long.How much area will it cover in 5 revolutions? (Use pi=(22)/(7))

The diameter of a garden roller is 1.4m and it is 2m long.How much area will it cover in 5 revolutions? (Use pi=(22)/(7))

The radius of a roller is 0.7 m and it is 2 m long. Then the area covered by it in 10 revolutions is

A road roller is of diameter 1.75 m and length 1 m. How much ground can be pressed with it in 200 revolutions?

The diameter of a roller is 2.4 m and its length is 1.68 m. If its rotates 1000 time to level a ground. Find the area of the ground.

The diameter of a roller is 120 cm and its length is 84 cm. The roller makes 500 complete revolutions in pressing a ground at the rate of 75 paise per square metre.

A field roller, in the shape of a cylinder, has a diameter of 1 m and length of a 1 1/4 m. If the speed at which the roller rolls is 14 revolutions per minute, then the maximum area (in m^2 ) that it can rollin 1 hour is : (take pi=22/7 ) एक बेलनाकार फील्ड रोलर का व्यास 1 मीटर लंबाई और लंबाई 1 1/4 मीटर है। रोलर यदि एक नियमित गति से प्रति मिनट 14 चक्कर लगाता है, तो उसी गति से एक घंटे में यह रोलर अधि कतम कितना क्षेत्रफल (मीटर वर्ग में) समतल करेगा? ( pi=22/7 लीजिए)
