To find the area of the road, we need to find the distance covered by the road roller in one revolution and then multiply it by the total number of revolutions.
The distance covered in one revolution can be calculated using the formula:
Distance = π * diameter
Given that the diameter of the road roller is 84 cm, we can substitute this value into the formula:
Distance = π * 84 cm
Since we need the area in meters, we need to convert the distance from cm to meters by dividing by 100:
Distance = (π * 84 cm) / 100
Now we can calculate the distance covered in one revolution. Using the approximation π ≈ 3.14:
Distance = (3.14 * 84 cm) / 100
= 263.76 cm
Finally, we can calculate the area of the road by multiplying the distance covered in one revolution by the total number of revolutions:
Area = 263.76 cm * 600 revolutions
= 158,256 cm²
Since we need the area in square meters, we need to convert the area from cm² to m² by dividing by 10,000:
Area = 158,256 cm² / 10,000
= 15.8256 m²
Therefore, the area of the road is approximately 15.8256 square meters.
