With 5 revolutions, the road roller will cover a circular area equal to the total distance traveled by the outer edge of the roller. The circumference of the roller can be calculated using the formula 2 x π x radius. In this case, the radius is half of the diameter, so it is 70 meters. Therefore, the circumference is 2 x 3.14 x 70 = 440 meters. With 5 revolutions, the road roller will cover a total area of 5 x 440 x 150 = 330,000 square meters. **

With 5 rotations, the road roller will cover a circular area equal to the total area rolled over. The formula to calculate the area rolled over by a road roller is A = πr^2, where r is the radius of the roller. Given that the diameter is 140 m, the radius would be half of that, which is 70 m. Therefore, the area rolled over by the road roller with a diameter of 140 m and a width of 150 m in 5 rotations would be 5 * π * 70^2 = 77,000π square meters. **
