hey mate
area of tyre is= 314cm^2
pi r^2= 314
the vale of pi is 22%7 so
22%7×r^2=314
r^2=314×7÷22
r^2=2198÷22
r^2= 99.9o
r^2= approx 100
r = 10
so we find the radius of the tyre
now
the circumference of tyre = 2×pi× r
= 2×22×10÷7
= 62.85 cm
so the tyre will cover the distance in 10 rotation.
= 10× 62.85 cm
= 628.5 cm
i hope its help you that's your answer
