Question

the diameter of a wheel is 1.26 metre how far is travel in 5 revolution

Answer 1

The diameter of wheel is 1.26

So the radius is 1.26/2 = 126/200 = 63/100

The circumference of circle is 2(pi)r = 2*22/7 * 63/100=496/100=4.96

After 5 revolutions , distance covered = 5*circumference= 5*4.96=24.8 meter.

$\huge\underline{\purple{\bold{Given}}}$

diameter =1.26m
radius =1.26/2m

change into cm
1.26/2×100=630cm

now

circumference of wheel= 2×pie ×r
➡2×22/7×630=3960cm

for 5 revolution =3960×5=19800cm

change into meter=19800/100=198m
