Answer:
549.5m
Step-by-step explanation:
the radius of the circle is 7m
:- circumference of circle is pie × radius
cf(circumference of circle ) = pie × radius = 3.14 × 7 = 21.98m
if the roller required 25 revolution to level the road then
cf = 21.98m to find the length of road,
cf × total revolution
21.98 × 25
= 549.5
