Question

The diameter of a wheel is $2.8m$. How far will travel in $1000$ revolution?

Answer 1

Diameter of wheel $=2.8$

Total no. of wheel revolution $=1000$

Circumference of wheel $=\pi D$

$=3.14\times 2.8$

Total number of revolution$=1000\ast 3.14\ast 2.8$

$=8792$ m

Hence, this is the required answer.
