Kilometers 31211

The road roller has a base diameter of 1.2 m and a length of 180 cm.
a) how many times did he turn on the road when he walked 2 km during work?
b) what is the largest area it can cover if it turns 1000 times?
c) how many kilometers will he travel if he covers 1050 m of road 3 times?

Correct answer:

n =  531
b =  6785.8401 m2
c =  3.15 km

Step-by-step explanation:

D=1.2 m l=180 cm m=180:100  m=1.8 m s=2 km m=2 1000  m=2000 m  o=π D=3.1416 1.23.7699 m  n=s/o=2000/3.7699=531
n2=1000 S1=o l=3.7699 1.86.7858 m2 b=n2 S1=1000 6.7858=6785.8401 m2
s3=1050 m km=1050:1000  km=1.05 km  c=3 s3=3 1.05=3.15 km
