Answer:
19,800,000 cm² or 1980 m²
Step-by-step explanation:
the length of the roller is 1m which is 100 cm
And in order to find the circumference of the roller we will use the following formula:
π x D
22/7 X 84
264 cm
in order to find the length of the road we will multiply 264 by 750
the answer for that would be 198000 cm
the width of the road, it will be equal to the length of the roller, which is 100 cm.
find the area of the road:
198000 x 100
= 19,800,000 cm² or 1980 m²
